As much as it is a blessed idea, I do have two qualms, though:
First off, I wonder how it’ll work, with non-Microsoft bloggers hosted on a Microsoft server. It all depends on the good faith presented by the company over time.
Secondly, writing technical content in Hebrew is a bit tough, and becomes a whole lot worse when you have to do it online.
The best of luck to all the new (and old) bloggers. I hope you prove I worried for no reason. :)
