Nice list over on Darren’s blog of signs you need a break from your blog. But I’ll add:
#9: you blog about blogging.
#10: you attack an A-lister by saying he’s an echo-chamber enabler and only writes to get on TechMeme.
#11: you say “TechCrunch this” and “TechCrunch that.”
#12: you go to Twitter and write “I’m blogging.”
#13: you tell your boss you aren’t merely reading blogs, you’re doing customer research.
#14: you have taken your son to so many blogger meetups that he starts his own blog to protest.
#15: you know the CPMs of a dozen other bloggers’ ads.
#16: when you say “Nick” “Om” “Mike” “Shelley” everyone around you knows who you are talking about.
