I found Firefish which is a better alternative to the standard Mastodon application. It’s compatible with Mastodon and has better features. It allows users to create web pages and the character limit is 3,000 instead of the 500 on Mastodon. It feels like a good limit for the type of site that it is. Plus this means that it can handle long posts from users on customized Mastodon instances.
There are, actually. Since Misskey’s culture are different from Mastodon’s, they have been implementing more features than Mastodon from the start, and Misskey’s APIs are different from Mastodon’s so there will be many weird quirks when accessing Mastodon (even weirder if it’s a Mastodon fork such as Glitch-soc, Hometown, Fedibird,… since they use older Mastodon versions as base) instances from Misskey instances (though Firefish devs are improving this by implementing Mastodon APIs and several Mastodon features). Also note that Misskey caters more Japanese users more than Mastodon, people who aren’t familiar with Japanese culture may also even Misskey userbase and features odd and different as well
i myself have been active on calckey/firefish, hajkey and iceshrimp instances, and never had a problem interacting with people on mastodon forks > there had been some backfilling issues, but they got solved > but federation problems do exist: so far, it is not possible for *key users to interact with lemmy instances; also link posts from kbin do not show up on *key timelines
