This is something I'd be interested in, I was actually working on one with XF1 before but it was a bit moot because XF1 development was extremely annoying.
I'd be interested assuming there's enough demand for it. I think it's a great community addition.
For some reason, money hasn't been my best motivator, and it can be a bit hard to find add-on ideas that I'm truly interested in that also pay the bills. Blogging might be pretty cool - I'll certainly look into it again.
