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.
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
