While the whole mini-msft seems to be an interesting blog these days, I personally just don't buy into the anonymity thing. I don't know, and I can't explain why - personally I just feel wrong about the idea. Second, there is a very high risk that it might end wrong for the blogger - the first thing that comes to my mind is that this would make many many bloggers sad.
I have my own feeling on who Mini-Microsoft is... I'm not going to say who because I just don't believe that I'm right, and most importantly, I don't want to cause random harm by emitting a stupid suspicion. However, I am thinking that:
1) Mini-Msft is probably a real Microsoft blogger too, because he loves to share his opinion to others. So it seems logical that he might have a real blog in addition to the anonymous blog, correct?
2) And all you have to do is compare his style of writing with the style of writing of any other Microsoft blogger.
Well, that would not work if Mini-Microsoft intentionally changed his style of writing in order to cover his tracks. But, even worse, what if an innocent person ends being accused?
