I rather like mastodon compared to the other implementations of activitypub (Misskey, Friendica and Pleroma). What I'd really like is to build my own activitypub server and client, but it's so hard. I'm going to keep using mastodon for now, but it sucks that the best activitypub implementation is basically a twitter clone. I'd really like something with a layout more like Facebook. Most of the people I try to convert to mastodon don't like twitter. I want to give them Friendica, but it needs a lot of UI work and a nice android client to really be useful to them.
