Seven deadly sins of blogging?

There is some discussion at the moment of the seven deadly sins of academic writing. I wonder what would be the equivalent in blogging?

1) 'Laziness'. I can't, for instance, be bothered to think up seven (or to tell you where the discussion about writing is taking place) so here are four 'sins' to be going on with.

2) 'Repeating news over and over and over again'. Did you take up blogging only to become part of closed self-referential group who only seem to read each other's stuff'? For goodness sake, most people can find discussions if they want to - you did! if you have nothing much to add, why not just let it go?

3) 'Getting guest scholars in to give their opinion'. Seriously. Don't mind the jokey ones, but what the hell is going on when people get eminent scholars to speak on a topic already spoken to death by other eminent scholars?

4) 'Becoming a part of the establishment'. Since when did advertising books that publishers have sent you become such an industry? Most publishers are nice people (until they change your title to something dumb and put a weird picture on the cover of your latest masterpiece - b*****ds). Do we really need to hear about your recent love affair with one of them (especially when they prefer you to us and don't send us books - b*****ds)?

5) 'Putting people down for absolutely no good reason'. Be humble. You don't know much, after all. Didn't your studies even teach you that!?!

6) 'PEOPLE RANTING ON AND ON AND ON ABOUT THEIR PET PEEVE (HAVING LEFT THE caps lock button pressed).'

7) Saying you are only going to do so much (e.g. have only four sins and not seven) and then going on long after you should have stopped!

8) Having no idea how to count, reason, or any of the other useful tools which most normal people possess, never mind the academically inclined.

9) Oops!
