If nothing else, the article is great for a breakdown of the features of Firefish. I've been a user for 2-3 months and didn't know a lot of the info covered.
On a related note, I was on firefish.social but it was very buggy for me after a while. Thought about throwing in the towel but eventually realized that it was instance specific.
I have since migrated to calckey.world (Calckey -> Firefish instance that didn't change its name) and the experience has been buttery smooth.
I'm also experiencing a lot of issues with firefish.social instance, still looking at some other small instances to migrate for the time being before maybe moving back. Based on https://joinfirefish.org/join/ and the dev update versions it looks like it's still an alpha server, hopefully it won't push away users since it is the flagship instance. I like it over Mastodon.
Yeah I like it over Mastodon as well. The UI/UX feels more modern. The only downside is that the majority of the Twitter-alternative fediverse is on Mastodon, so I have to run 90% of accounts through 'search' to follow them.
The article does touch on some of the main instance's issues towards the bottom too I just found out.
