How to know you've been twitter too much-

-You have over 100 friends thanks to followfriday
-You know what followfriday is
-You've used followfriday to endorse someone else
-You've tweeting too much and they've cut you off for an hour
-You've downloaded tweetdeck so that you can beat the system and keep on tweeting
-You've personalised your tweetdeck

And my final thing (for now) is...
-You've had a dream about someone on twitter.

Just me then?
