Just when you thought the days of web directories were over... that speculative blog post by Fluent Simplicity listing a few of the brands with Twitter feeds is reborn - as a standalone site at Social Brand Index. I still say a publicly editable wiki would be far more practical. Still, a glance down the page of represented brands is quite interesting, and there are several hundred listed.
