For some obscure reasons that have to do with spam but that I failed to understand, comments are not allowed anymore on posts older than 30 days on weblogs.asp.net blogs.
This is very frustrating and goes against the very principle of blogs. I'm really sorry about that, but there's nothing I can do oher than send internal mail to complain about it (which I already did). I just hope that this limitation is removed as soon as possible.
For now, if you have comments, you can send them to me using the contact feature of the blog, and I'll store them until I can post them for you (yes, amazing as it may seem, even I can't comment my own blog).
