The World Bank's Development Impact blog, here, is my main blog to keep tabs on.
It is a bit technical, but those are taking/have taken the Impact Evaluation in Developing Countries course will enjoy it.
But there are plenty more out there- with a range of styles. To see a list of some favorites, courtesy of Owen Abroad, click here.
A number of development economists also have pages with interesting links, rather than blogs. I include just a couple here:
Chris Barrett's Favorite Links, here. .... actually the site has changed... I guess links are a thing of the past..
