Q and A on Beehaw - what's the vibe?

So this is a bit of a meta-question. I was going to post a question about tech (for context I am looking for a tablet/iPad to read journal papers) so I headed to the technology community. But all the posts are news articles and the description is along the lines of 'post happenings and innovations in tech...' so I chickened out. Same over at science and humanities (I was thinking a more acedemic community might be up for a convo about journal reading)...

I know Beehaw is really friendly and it probably wouldn't matter if I posted random questions in the "wrong" spot but I would like to be able to target my questions and convos and not just put everything in chat and AskBeehaw. But maybe that's the idea. News type posts by topic and convos in other communities to maximise the relatively small community?

I'm really interested to know what 'rules' other people use to decide where to post non-links. Or any more formal guidelines - Am I missing something?

Edit: and yeah I did (over)think about posting this in Beehaw support but I am more interested in hearing about other people's thoughts then asking a help question
