Amber MacArthur has published Top 5 ways not to be annoying on Twitter. They’re mostly common sense but useful all the same, and I have one more to add that’s actually less about being annoying and more about not being trigger happy with the old keyboard keys.
5a. Don’t hit the ‘return key’ before you’ve finished typing your tweet. I did this today – luckily I’d actually completed the tweet, but it made me realise how easy it is in a lapse of concentration to hit return half way through typing a sentence and alerting all your followers to your incompetence. Note to self: Get another coffee and concentrate, dammit.
