I like the fact that mastodon.social is the biggest instance, but I would leave for an instance that is paid only, say $10/month, has a cool domain name, and thus can afford to raise the rate limits.

Mastodon.social feels like early Twitter both culturally (good), and fail-whale-wise (not good).

@gruber what could be cooler than @[email protected]?
@radu I’ve given that a lot of thought but I don’t want to be responsible for the instance. I think.
@gruber @radu Get a hosted server. I use masto.host, and it works great.
You should probably have a different domain though for SEO reasons. Like daringfireball.social.
