This is actually the second time on the WotC site that Death Frost Doom has been mentioned. It was talked about in the podcast just before the holidays in their "What to buy for gamers" podcast. They mentioned how great the adventure was. I went and bought the PDF of it just because of it.
This is actually part of a series of interviews by WotC of them talking to bloggers in the D&D community. They are actually branching out and talking to the people that are popular in the community and highlighting what they are doing. Everything we'd actually want them to do to start engaging the community more.
Plus it actually mentioned and talks about the fact that they aren't playing 4E, I think that alone would make the naysayers cream their pants.
