Last time I ended up at Racketboy it fucking sucked. Articles full of errors and worthless top ten lists. To be fair though, I just checked it and it doesn't look so bad now. I used to read UK:Resistance, but it died a death a few years ago now. I check Game|Life over at Wired as Chris Kohler does actually know his stuff, although again over the last few years it's gone downhill - it's become little more than press release regurgitation. It's a decent enough source for mainstream gaming news I suppose. That's actually about it for the gaming blogs.
I sometimes visit Kotaku and for the most part it is quite informative, however it is seriously hurt by internet trolls.
Here, IGN (just PSP & Current Events), along with being a lurker on neogaf. As for news sites (I don't really consider them blogs). I mostly keep to Andriasang.com, gpara.com & Famitsu.com/game/
Engadget, Joystiq and TUAW. I also randomly check HG-101 to see what new articles there are, and the UK PlayStation blog on a Wednesday to see the week's PSN releases.
I've started to migrate more to Destructoid, although it definitely suffers with idiotic comments and the odd obnoxious blogger (here's lookin' at you, Jim Stirling - you used to be funny by telling the truth, but now you're a parody of yourself).

I follow a few blogs, good ones don't get updated too often, and the rest just re-blogs stuff from other sites, but they aren't agregattors no sir! Holy crap, haven't been there in years and they still have that crappy all-text, eye-killing template...
I found some interesting Japanese blogs over the years. Unfortunately I cannot read Japanese, but the pictures on it's own are interesting to watch. Bakutendo: http://bakutendo.blog87.fc2.com/ Mainly Famicom, dumping carts, hardware mods and so on. I modified my FDS RAM adapter based on his photos ayasuke: http://ayasuke.exblog.jp/ pirate gear, clones, flash carts and so on.
Yes Racketboy has gone really downhill, theres basically no content now and "lets all play together" events where they play some game everyones played anyway a thousand times. Kotaku is my daily blog but I do try to avoid the comments. There was also an article just today by one of the head writers who claimed to have never played Doom in his 17 years of gaming before today. That scared me and makes me wonder who in the world is working at that site. I like Destructoid, I need to make it there more regularly. Their reviews, though late, are pretty well done and go against the usual game hype machines of IGN. And of course I try to check here daily.
Not that I read Kotaku (or any Gawker blog), but to be fair, in my 24 years of gaming I've probably played Doom for a total of about 15 minutes. And I'm sure I could write much better articles than some of the clowns they employ.
If it was a PC-only game from the same era that'd be understandable, but Doom is one of the most widely ported games of all time. How the hell has he managed to avoid it? It's weird that someone would destroy their own journalistic reputation like that, but then: Kotaku.
