I don't feel like there are many <i>friendly</i> places on the internet, where people are helping each other and beginners (or even not-to-smart people) can talk.<p>Maybe forums for specific software?<p>Now that I think about it, the fitness related reddit subs are kinda friendly comparing to technical ones.
hackaday is pretty interesting for general purposes<p>I think individual topic subreddits are valuable too, but their quality varies depending upon popularity and moderation (a lack of both, usually)
