that out of all the Gawker media sites, Jezebel/Groupthink gets along best with io9 and the Observation Deck?
Kotaku posts good articles, but the comments section is a mess. Deadspin and Lifehacker show up once in a blue moon. Gizmodo and Jalopnik just kind of... exist. And Gawker is Gawker (though there's obviously crossover with Crosstalk).
I dunno, it just seems like I usually see a fair number of jezzies and GTers on io9, and they seem to be a pretty friendly place. Same with Observation Deck (though I don't go there that often). Good articles, chill comments section, the whole works. I like io9.
