Who Did Six Apart Acquire?

San Francisco-based blogging startup Six Apart has made a significant acquisition, we heard today from someone with knowledge of the deal. “Significant” in the sense of a possible strategic shift for the company, if not in terms of deal size. It will be announced in the next few days.

Who did they acquire? Put your best guess in the comments. First comment that is correct gets a 2 GB iPod shuffle with “I Love TechCrunch” engraved on the back.
