RE: translation feature requests: this is probably not going to happen - if it does, not for a long time. The financial risk is too high.

My response to this is also that while right now it may feel like a Tower of Babel, the nature of mastodon instances would suggest that communities will settle over time and this problem will alleviate itself. The most I can offer immediately is the ability to copy toot text so you may paste in a translator of your choosing

@eurasierboy Could toots be tagged with languages used (declared by too author) and people be able to filter their timelines for only a set of languages? sure it'll be imperfect, but possibly useful for some.
@rwzh until the API supports such tagging and filtering, this will not be capable, sorry~
