io9 for science and geek stuff. Less for film and TV because the hipster entitlement they've been running with in a couple of regular strands there is terrible, factually inaccurate writing that hurts the writer and the site. Thankfully they're getting back on top of that and their stuff is still far better than most other people's.
Kotaku for gaming stuff. Also for Snacktaku, which is one of my food writing favorites.
Bleeding Cool because it has a consistently interesting and different perspective. It also has a reputation which is in the dirt in some areas and that's largely undeserved. At least in part because I write (unpaid) for them and I know just how good my stuff is there.
SFX, again partially because I write for them and partially because the spread of content, especially with the reader bloggers, is really good.
The Register is good for tech and VERY high end computer industry stuff. I read it for the occasional Top Gear-style engineering pieces and occasional snark.
Lifehacker and Gizmodo are both semi regular check ins for tech stuff and life...hacks.
SciFind because their essay model is interesting, they come up with really skewed angles that are really fun.
