Twitter is observing its seventh birthday today — that is, it’s been 7 years since Jack Dorsey’s stirring “just setting up my twttr” tweet. In Twitter’s celebratory blog post, it says it now has “well over 200 million active users creating over 400 million Tweets each day.”
It’s impressive that Twitter is still here and still doing great — an extremely rare success. Twitter has permeated society on a level that only a small handful of tech companies ever have. And it certainly has had several opportunities to screw up.
