Question: Has there been any discussion about denoting the experts of certain topics, for example MVPs or Microsoft employees in the small profile icon? 

This way users can quickly distinguish between random internet morons like myself, and the ones accredited with their chosen speciality?

Answer: 
MVPs are awarded by Microsoft for those that help spread the word to the community more than it is to experts. The more you know...

Regardless, this isn't a Microsoft (or any other company's) site, and the only currency on here is reputation. We vote up answers so that you can quickly distinguish between random morons and decent responses.
Give a MVP a badges and letting them start with 100 reps may be good if it gets more of them to use the site. Otherwise let everyone live by their rep.
