Ok, not me, but my blog. And I need your advice, please

The question: what are the pros/cons of moving my blog off the msdn platform?

 The Pros

• Individual Brand Equity- Look, let's face it. I'm not going to be at Microsoft forever. At some point, I move on and then, what happens to the "brand equity" that I've built as a blogger?
• Isn't it better to have a global microbrand that is reflecting of me as an individual than simply as a Microsoft blogger?
• Won't it be much more difficult to move my legion of adoring fans ;-) at a later date rather than an earlier one?

The Cons

• Inertia-this URL/RSS is already out thlere. Will I lose a lot of people if I move now seeing as how people are creatures of habit and won't update their feeds?
  
• Platform-MSDN gets more exposure than I ever could on my own. New audience/community members won't hear/become aware of my 'incredibly exciting blog' otherwise.

One Possible Solution

I can set up another blog and dual post and point those of you reading this blog to the new URL/RSS feed. Will that work?
