Well they are new to me.
D20 Dark Ages
D20 Dark Ages is run by Stelios a writer and historian. The blog mostly focuses on his one gaming exploits from the time period of 1989 to now. There is a strong old-school vibe to his blog and details on what really were the Dark Ages in my mind as well, the period of the death of TSR but before 3.0.
Interesting site and I hope to see a lot more.
Coniccritique was turned on to me by an old friend. It's not an RPG blog, but as the name suggests, a comic review blog. There is quite a bit of good critical insight. It is a work in progress, but the writing is good.
I enjoyed his reviews of Batwoman and Justice League Dark and honestly he reminded me why I was reading two of the best New52 comics.
So go out read them, follow them. I am expecting them both to get bigger and better.
