Everyone still on the hellsite: Twitter is burning but Mastodon is not usable, bluesky is meh, and I don't know anyone on T2.

Me: I can toot from an emacs buffer to Mastodon, how much more usable do you need it to be?

Everyone still on Twitter: ... What is emacs?

Hello again, everyone. I’ll give Mastodon another try now that the bad place is collapsing. Can’t wait to entertain you with my toots and listen to yours.

Tooot vs Metatext: Home Timeline

Peter Ullrichpul
2022-12-17

I’m trying out different Mastodon clients on iOS. So far, tooot.app is my favorite, followed by Metatext. They both mimic the bird side client well enough to make switching painless. What’s your favorite client?

Great advice! Sometimes even a:

is enough!

@eleni true! I always wondered how/why apps download the Gif from e.g. Giphy and upload it into the chat. Why not just send the URL and let the other client download it? 🤔
