Jeez yu guys are harsh. They're asking for advice...
What I would say is...
go for a high level of transparency in your editorial process, as if the making of the story is part of the story itself; that sounds wankerish but I think it is this transparency that lends an air of.. well not impartiality, but justified opinion, the best example of which would be Giant Bomb; they talk about and film and expose everything; the Socratic dialog is key to building trust in such a hilariously jaded and spazzy audience
keep the Verge layout because you know that shit is hot
take all of your editorial tools and spread them out before your team in a manner not dissimilar to the way Dexter lovingly unrolls his killing implements; don't make any assumptions about how blogging "used to be" but rather pick and choose each weapon for the appropriate kinds of communication; no reason you can't have a superstar site, AND twitter feed, AND linked Facebook and G+ communities AND podcast.... stay flexible
you guys have been skulking GAF for years, take note of some of the things that are counterintuitive yet supremely sticky on GAF, like the easy delineation of forum topics ("Games" and "Everything Else", rather than a million sub forums that squelch cross-communication), and also the craigslist-like refusal to make radical changes to the site layout (which is both good and bad in GAF's case but it's always really familiar and I think people like that)
obviously try and steer away from the trashy stuff like gamer tattoos and cakes
I think there's a way to somehow combine a story and a lively discussion in the same web page that's very effective; Ars Technica sort of does this but you end up being teleported to a forum; Joystiq and Kotaku were/are overrun with snarky one-liners and knee-jerk reactions; the audience turns on a dime as you all well know so I'd just say spend some real time figuring out your communication strategy
and I think almost above all, don't bury the writers, make them front and centre and let the personality clashes fly if they must, as long as it's all on topic; I think from the old 1UP Yours crew you could see how team dynamics can really work, almost like the 3-editor reviews which I also liked form the older gaming mags; I like seeing a little image even on each story so I can sort of put a face/icon to the "voice" of each story... much like GAF
sorry this ended up being all tl;dr but there you go
