Do Google & Facebook really produce the best PR peeps?

This week, Business Insider put out its Top 50 Communicators in Tech list: http://www.businessinsider.com/the-pr-50-the-most-effective-communications-professionals-in-technology-2012-7

Impressive and very proud to know a few of em. But kind of ridiculous and irritating that of 50, more than HALF are either at Google, Facebook or Yahoo or came from one of them (to land at hotties like Twitter, Pinterest, Klout, AirBnB, Square). Toss in a couple each from MS, Apple and LinkedIn, a few from VCs, and a small set of agency peeps and there’s your list.

Oh, and just over 10% of the 50 are from anywhere other than the SF/SV area. Seriously.

I’m not doubting these are awesome companies and SF does have a lot of tech marketing talent. I’m not arguing that these 50 are KILLER communicators. But there are good PR folks across the US, in lots of different companies and agencies.

Other PR friends, does this also ruffle your feathers a bit?
