The # tag on Twitter is great! Whoever came up with the idea deserves a pat on the back.
I was thinking I should make a use for it myself, with a story!....
All you have to do is continue the line from a previous tweet you see with the # tag #tweetytale at the end of it, and put the same tag at the end of your tweet.
 
But won't everyone see different tweets and write different continuations?
