What is the problem Twitter trying to solve?

Twitter was orignally Twittr. It was a pivot from a podcasting company that didn't get any traction. When it launched it didn't have retweets.

TechCrunch's article from 2006 on Twittr is interesting: https://techcrunch.com/2006/07/15/is-twttr-interesting/

I'm not a twitter user, but in my view if you want to publish an opinion you might as well to put it in your blog. And when nobody reads it, make a conclusion on whether you should continue that habit or not.

If you want to reach out to people, better use email? Or if you wan to chat with people, use IRC, discord, whatsapp, telegram or something.

Centralized press releases plus opinion fights.

Like now or when it started?
