Outside of what is, despite impressions, a very small regional niche, TechCrunch the biggest source of PR and exposure, and in fact isn't even on the radar for a lot of folks.

One key to success is knowing your audience, and for many companies it's extremely unlikely that Arrington is a member of their audience. Those companies really shouldn't be worrying about going out of their way for sake of a blurb from him.

Missed my point. While TC gets on my nerves at times I like the site and they break news pretty well. I subscribe to their RSS - I'm not anti-TC.

My comment was trying to state that people can get too caught up in their own world. For me, that's TC/Mashable/ect. Building a successful business (which I admittedly haven't done yet) does not require being featured on TC (or other) blog. Does it help? Of course. But it's got a finite value which you have to make sure you don't overestimate.
