Learn Hardcore Russian: Хорошо бы однажды устроить совместный стрим и поговорить о мотивации. - It would be nice one day to do a joint stream and talk about motivation.

Without бы, just Хорошо устроить совместный стрим sounds odd or like a fragment of a different structure. Бы is what gives the sentence that “would be nice / I wish” nuance.

Why is there no было in Хорошо бы? Shouldn’t it be Было бы хорошо…?

Both are possible, but they are slightly different in style and emphasis:

Было бы хорошо однажды устроить совместный стрим…
Very clear, complete structure: It would be good to one day set up a joint stream…
Хорошо бы однажды устроить совместный стрим…
More colloquial and compact. Literally it omits было, but it is understood:
- (Было бы) хорошо бы однажды устроить…

In everyday speech and informal writing, Хорошо бы… is very common and completely natural. It’s like English dropping “it would be” and just saying “Would be nice to…” instead of “It would be nice to…”.

Why are устроить and поговорить in the infinitive? Why not устроим, поговорим?

In Russian, after impersonal phrases of desire or evaluation, you typically use infinitives:

Хорошо бы устроить… – It would be good to arrange…
Надо поговорить… – It is necessary to talk…
Можно поехать… – It’s possible to go…

The infinitives устроить and поговорить are like English “to arrange” and “to have a talk” in this type of structure.

If you say устроим / поговорим, you make it a direct 1st person plural statement:

Давай(те) устроим совместный стрим… – Let’s set up a joint stream…
Мы поговорим о мотивации. – We will talk about motivation.

So:

Хорошо бы устроить… = hypothetical wish, more “impersonal”
Устроим… = a direct, decided action by we/us

What exactly does устроить mean here? Why not сделать стрим or провести стрим?

Устроить literally means “to arrange / organize / set up.” In this context:

устроить стрим ≈ to set up / organize a stream
– implies arranging it, deciding, setting everything up.

You could also hear:

сделать стрим – very colloquial: do a stream
провести стрим – hold / run / host a stream (focus on the event actually taking place)

Nuances:

устроить стрим – emphasizes planning/initiating the event.
провести стрим – emphasizes carrying it out.

In the sentence, устроить works well because the idea is more about “one day set this up” than about the technical act of hosting it.

What does совместный mean exactly, and what does it agree with?

Совместный means “joint, done together, collaborative.”

совместный стрим – a joint stream, a stream together (e.g., with another creator)

Grammatically:

совместный is an adjective in the masculine singular nominative form.
It agrees with стрим, which is masculine singular (nominative) in this sentence.

If the noun changed, совместный would also change:

совместная трансляция (feminine sg.)
совместные проекты (plural)

Why is однажды used here? How is it different from когда-нибудь?

Both refer to an unspecified time in the future (or sometimes past), but with different nuances:

однажды – one day / once (on one particular occasion)
- Suggests a specific, single occasion, even if you don’t know when.
- Often a bit more “story-like” or slightly more literary in tone.
когда-нибудь – someday / at some time or other
- More vague: at some point, maybe, who knows when.
- Can sound a bit more indefinite or unsure.

So:

Хорошо бы однажды устроить совместный стрим…
= It’d be nice to (at some specific future point) do a joint stream…
Хорошо бы когда-нибудь устроить совместный стрим…
= It’d be nice to do a joint stream someday (at some point or other)…

In many contexts they’re close in meaning, and you could swap them, but однажды feels a bit more like “one particular day in the future.”

Why is поговорить used instead of говорить? What’s the difference?

Говорить and поговорить differ in aspect:

говорить – imperfective: process, duration, repeated action.
- to talk, to be talking, to speak (in general).
поговорить – perfective: a complete action with a natural endpoint.
- to have a talk, to talk for a while / to discuss and be done.

In this sentence:

…и поговорить о мотивации.
– suggests having a specific, bounded conversation about motivation (as part of that future stream).

If you said и говорить о мотивации, it would sound more like an ongoing activity:

…and be talking (a lot / generally) about motivation.

So поговорить matches the idea of “have a talk/discussion (at that time)” rather than an endless speaking.

Why is it о мотивации and not про мотивацию? Are о and про interchangeable?

Both can be used to mean “about,” but:

о + prepositional case (о мотивации)
- Neutral, standard, used in both spoken and written Russian.
- Slightly more formal than про.
про + accusative (про мотивацию)
- Colloquial, very common in speech.
- Often feels more informal / conversational.

So:

поговорить о мотивации – perfectly standard, neutral.
поговорить про мотивацию – more casual, spoken style.

They’re largely interchangeable in everyday usage here; the choice is about style, not correctness.

Why does мотивация become мотивации? What case is that?

Мотивация is a feminine noun. In о мотивации, it is in the prepositional case after the preposition о:

Nominative: мотивация – motivation (as a subject)
Prepositional: о мотивации – about motivation

Pattern (for many -ия nouns):

-ия → -ии in the prepositional singular:
- информация → об информации
- ситуация → о ситуации
- мотивация → о мотивации

Can the word order change? For example: Хорошо бы устроить однажды совместный стрим?

Yes, Russian word order is fairly flexible, and you can move однажды around:

Хорошо бы однажды устроить совместный стрим… (original)
Хорошо бы устроить однажды совместный стрим…
Хорошо бы устроить совместный стрим однажды…

All are grammatically correct. Differences are mostly about rhythm and slight emphasis:

At the beginning (однажды устроить…) – one day is highlighted.
In the middle (устроить однажды совместный…) – neutral, but slightly less smooth than the original.
At the end (…стрим однажды) – “one day” is almost an afterthought.

The original version sounds very natural and smooth in everyday Russian.

Who is the subject in this sentence? Is it “I” or “we”? Why is there no я or мы?

The sentence is impersonal; it has no explicit grammatical subject:

Хорошо бы однажды устроить… и поговорить…

This is common in Russian with structures expressing wishes, necessity, possibility, etc.:

Надо поговорить. – We/I need to talk.
Хорошо бы отдохнуть. – It would be good to rest.
Можно сходить в кино. – We/I can go to the cinema.

Who is implied?

Context-dependent. Here it’s most naturally “we” (the speaker and someone else doing a joint stream).
If said by a single streamer inviting another, it could be felt as “you and I” together.

Russian often avoids explicitly saying я or мы when the meaning is clear from context and the verb is in infinitive with such impersonal phrases.
