What is Threads?

This article is a draft! A lot of info might still be missing and the page might change at any time.

Threads formerly Project 92 and Barcelona, is a software project by Meta (the company behind Facebook, Instagram and more). It is a micro-blogging platform and a Fediverse alternative to Twitter.
While the media praises this as a 'saner version of Twitter', that will eventually replace it, in the Fediverse it is generally considered a bad thing.
There is even a pact for Fediverse admins and mods to block Threads and all it's instances. See fedipact.online. According to polls (1, 2) about 65% - 75% of Fediverse users are in favor of blocking Threads.
