@ali the problem I see is lack of sufficient critical mass. Only some of my friends are on Mastodon and I am a bleeding edge adopter for tech.
The mistake here is to see these processes in a fatalistic way as if nothing can change them. The Web didn't just happen because everyone thought it was great, we spent a great deal of time thinking about adoption strategy.
Whitehouse.gov didn't just happen, we pushed Gore's people to look at the Web as the means of delivering his Information Superhighway. And we did that because I had seen how the IBM PC legitimized the micro-computer.
We have to look at how to extend Mastodon and make it 'sticky'. One way to do that in my view is functionality that integrates legacy Web Forums into the Fediverse so that we get the Facebook groups type functionality.
I am on a half dozen Facebook robot building groups (yes, the dalek in my avatar is one I built). I would much rather they moved to a different site so I don't get banned for 30 days for mentioning someone once made an actual musical of 'springtime for hitler' again.
If there was a Mastodon robot building interest group and prop builders were there, I would be there and so would most folk in the community. While there are people who only build daleks, most serious folk will build a dalek and then maybe R2 and then maybe a Robby or a B9.
There is a distinct community but it is fragmented across a dozen different forums and some (e.g Dewback Wing) seem to have gone. And none of them are really much good for structured discussion.
