Does the fact @TechCrunch is a suggested account mean   
   you are more likely to report favourably about twitter?

   Isn’t it a bit like accepting a free gift as a    
   journalist? They send you lots of lovely free traffic  
   for example.

this guy is onto something

I don't think it has anything to do with suggested accounts. TechCrunch figured out that when you write about Twitter, then Twitter users love it and talk about it. I think that's normal behavior (any story written by a major blog about HN would immediately get promoted and viewed here, for example).

The reason this doesn't work so much for other sites (writing articles about Facebook, for example) is because Facebook doesn't have the same meta-culture; Facebook users generally don't feel like there is anything special about their membership on the site. Also, sharing outside content/retweeting has not taken off on FB like it has on Twitter.

I wonder how that traffic breakdown would look if they only ever did pieces on actual news relating to twitter instead of pretty much daily news.
