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.
