author here. the reason we used michael arrington, ariana huffington and matt marshall is because they are the founders of the respective publications (not because of their current involvement).

for the featured in, you are right (it actually goes back to when we were expecting publicize to be featured in a tnw article as our design was being implemented and this was pushed back). because we've only been included & written guest articles, we will change this to as seen in.

update: we've fixed this to "as seen in".
