@mngrif Some people:

@cwebber@octodon.social - A programmer who basically started the ActivityPub W3C standard and continues to work on technologies in a similar vein.

@Liberty4Masses Not a bot but mostly posts Libertarian style memes.

@snder - good dude, runs the quey instance, tends to have respectful debates.

@Curator - The guy/girl who runs the art instance. Mostly reshares some of the better art from the instance.

@climagic I thins one is a bot but it does share rather useful and cool commands that do cool stuff.

@MOTT - Programmer, respectful and vocal in debates, pretty sharp.

@Taweret@octodon.social - real person (I think), posts mostly Star Trek memes and reflections.

@Gargron - Creator of Mastodon, coder, usually fairly response to relevant and respectful comments, seems to lean far left and while he has a tendency to overreact to many things I think that is partly the consequence of having too many eyes on him. He has good intentions I think though. At the very least good to follow if you want to see where the software is headed or just are similarly far left.
