Now that I’ve had the chance to try both (thanks to [email protected]), I can say that Mastadon seems more familiar to me as a former Twitter user. Despite being a Twitter spinoff, Bluesky seems to be trying to reinvent the flow of things. I’m not quite sure how hashtags (or their equivalent) work there.
I’m not sure which is better yet, as I’m too new to Bluesky to really form an opinion, but those are my initial impressions.
I’d like to see the National Weather Service and local government agencies start posting to one or both though, as weather and traffic are the only reasons I look at Twitter anymore, and I’d prefer not to support it at all.
