Hi, welcome to the Federation, on behalf of Spock, Sulu and the gang..
I still feel a bit "newby"ish welcoming anyone - but also a bit like a (Pluspora) old-timer, having also fled here from G+.
Not sure which of the hashtag potpourri brought you to me, but for sure philosophy & literature (just posted on this).
Your many interests seeking outlet/connection should do you well in pora* land, I think.
I'm a social scientist (among other things) and did a lot of research on social media, especially hearing my world of G+ was being destroyed by its parents and looking for re-settlement options. I focused on the pora* and MeWe worlds. Since we're "here" I'll just speak to this - I find that many of the people I met in the last months of G+, with my involvement in some forums and death-watch G+ groups, were very positive about pora*/Federation in general as well as specific regional and member pods/instances. (Had to learn the jargon!) And many of the tech and professional-focused people who interacted there - some heavy geeks as well as community and collection fans - ended up "here". (Whereas many who were mostly involved in photo and other topic-related communities on G+ went to MeWe, which has "albums" and groups, some supposedly "public" but really like FB and AOL, closed circuit).
All this to say - see what getting sleep finally on the weekend can do? - settle in, look around, and welcome to this very large swath of international interaction. (I'm not naturally, or by dint of profession, chatty, most of the time but your tag "talking" and having some energy after sleep and coffee are both kicking in, and the timing of seeing your "sharing" note.)
Tags do rule here, and work very well. If I might suggest, if you want to maximize the likelihood of running into some old Google+ connections, some of whom may have changed screen names, use the #gplusrefugee
and you'll be seen by others following or exhibiting those tags in their feed. Enjoy!!
