The Silicon Valley vs. Boston tech scene discussion is a tired one, I know. But today we’ve seen a number of Boston-area companies make a splash with some significance to the San Francisco Bay Area.

Here we go with the highlights:

—Burst Media, the Burlington, MA-based online ad distributor now owned by blinkx (a San Francisco video search company), has rolled out four online community channels to help advertisers target gamers, moms, sports fans, and (dare I say it) fashionistas. The new sites—called Giant Realm, MomIQ, Stadium, and Ella—encompass thousands of independent Web publishers and their audiences. The company calls this “a significant first step in the realignment of Burst’s publisher strategy following its acquisition by blinkx.” It’s also yet another example of tech companies trying to figure out how to distribute better-targeted ads to specific types of consumers.
