The majority of commercial software shops are probably developing on the MS stack. Smaller shops, startups, small online services are more likely to be on the LAMP stack. My shop is on the MS stack, and we will hire people with solid OO design, database design, and n-tier application architecture chops. The toolset isn't important. Likewise, when looking for a job, look for people making something you wants to make, with similar attitudes and interests to yours, and care less about the tools they're using. The comments at Stack Overflow are all over the map I notice.
