This month marks ten years since 140 character messages became part of our social routines. The little blue bird and its fail whale companion have been around since its inception, with celebrities, political figures and world leaders all joining the channel to give fans a glimpse of their lives, and their thoughts.

To mark the occasion, we came up with a list of 10 fun facts about Twitter, naturally in 140 characters or less:

  1. Hashtags were invented in 2007 and were at first deemed as “too techy”. #theywerewrong #hashtagsarecool
  2. Humans have a lot to say in just a few words. Over 500 million tweets are sent per day.
  3. Most Twitter users are on-the-go when they log in. 78% of users are on mobile devices as they scroll through and RT.
  4. Want your tweet retweeted? Post it late night between 10 p.m. and 11 p.m.. Users tend to check Twitter at home before going to bed.
  5. Say hello (or tweet, tweet) to Larry—that’s the name of the little blue bird icon.
  6. Looking to follow more people? Twitter won’t let you follow more than 2,000 people if you don’t have 2,000 people following you.
  7. Twitter makes the world go round, with 80% of world leaders using the social service to connect with people.
