FYI - I am not really active on this Hubzilla account ( isaackuo AT hub DOT toot DOT cat) any more. My active accounts are:
1) diaspora ( isaackuo AT pluspora DOT com firstname.lastname@example.org ) - most of my posts, including space technology ideas and politics. Note that diaspora does not federate with Mastodon, so you can't follow this account from Mastodon.
3) mastodon ( isaackuo AT mastodon DOT social email@example.com ) - I've been trying to participate more with discussions and stuff on my Mastodon account, although I never get any engagement on my posts
BTW, I have made UserStyles which provide multi-column stream to diaspora, Mastodon, tumblr, Hubzilla, Friendica. I find it really boosts the speed and ease of browsing through a lot of stream content. See here for how to:
@isaackuo It turns out I've been following your toot cat account but not your dot social account. That said, I mostly check just the retrocomputing hashtag and don't make a great effort to keep up with my stream here.
