Anonup is raising interesting issues about social media for me. It appears to be remarkable well "weeded" of trolls and bots. The audience is high level, loving, and erudite. There's none of the anger of Gab or idiocy of Twatter.
I post some things to Gab because I don't feel they do much for people here (e.g. article links with a pull quote). Some stuff like my photos it would be nice to have a mechanism to push to both. Anonup is like your peers and bosses are watching, so you had better put out quality stuff.
The one downside I see of a niche social media platform is you don't so easily get to promote people and content from obscurity as a "big name". Once I had 100k+ followers on Twatter I could magically direct attention to videos etc. For someone who had sung a special song, say, and put it on YouTube those thousand views would make their day and week.
Sometimes quality and quantity are in tension; other times not. One public square, or many?
As I mentioned in a previous reply/post - AU is a safe space for me - my go to place.
I float between IG, GAB & AU to get varying perspectives of current events.
Obviously, it's all based on who you follow and certain topics/interests but it's interesting to see the broad range of content.
I deleted FB years ago because it was just a cesspool of garbage, even though they were "friends".
Gab - Meh. I like what Andrew has offered as an alternative for social media but I usually know content prior to going on Gab because I saw it first on AU.
The frens on AU remind me of the anons from Voat.
On AU, everyone speaks their mind, shares info & supports one another.
There is no judgment on AU unless you are totally out of line or over the top.
Although IG is Meta (FB), many of who I follow share Twatter posts and since I'm suspended, I can get more info & perspective of who is saying what.
