I say no. It effectively competes with posts on the main forum - and instead of people having to properly think about issues, and respond to others - everyone runs off to their own little corner, to blab about whatever they want.
People can effectively do this at the moment through the forum (off-topic, or other) - its just more open, and more accountable.
I also personally think the focus has already shifted away from the "main forum threads" a little too much (maybe this is the intention?), and that blogs will extend this further?
