A comment on Blogs and Development from Enrique Mendizabal at ODI, very nicely explained (a while ago) how Blogs can help us in our work.

At its best, blogs can filter information from previously inaccessible sources; can convene different groups around a single issue providing a menu of options and links to further resources that conventional media finds it difficult to deal with; may offer the basis of a tightly knitted community of practice or interest group; and constitutes a cost-effective platform for individuals and organizations to join the global development debate.

We agree.
