I have been spending most of today on finding out how to validate hashtags. That resulted in http://stackoverflow.com/questions/36895543/which-characters-are-allowed-in-hashtags and a LOT of frustration. Untill I discovered twitter-text because someone mentioned it at aforementioned Stackoverflow question.
Why is it so hard to find?
Searching https://dev.twitter.com for "twitter-text"only yields two results. TWO RESULTS!!! And this software that twitter-text is seems to be defining standards for usernames, hashtags and more. Why does it then seem so unmentioned?
