Wikipedia: Twitter
Twitter (/ˈtwɪtər/) is an American microblogging and social networking service on which users post and interact with messages known as “tweets”. Tweets were originally restricted to 140 characters, but on November 7, 2017, this limit was doubled to 280 for all languages except Chinese, Japanese, and Korean. Registered users can post, like, and retweet tweets, but unregistered users can only read them. Users access Twitter through its website interface, through Short Message Service (SMS) or its mobile-device application software (“app”). Twitter, Inc. is based in San Francisco, California, and has more than 25 offices around the world.
 
Twitter was created in March 2006 by Jack Dorsey, Noah Glass, Biz Stone, and Evan Williams, launched in July of that year.

Twatter
A social networking and microblogging service for the sending of “one to many” messages via SMS or a web interface.
Used by the kind of twats for whom blogs and Facebook status updates don’t offer the sheer frequency of attention they crave.
Yah, I use Twatter all the time to stay “hyper-connected” to my friends. I’m a total addict - a real Twatterer!

I’ve joined twitter (or twatter as some call it) just in time for the ending of the 2019 Formula One season and the #AbuDhabiGP possibly a dead rubber as it were but at least it’ll be worth the watch
