I'm getting some great feedback on whether or not to cross-post and which blog should host what type of content. For the e-mailers, please post a comment to the blog itself. I want other people to see your ideas if possible. The general consensus is this- post technical content (and more of it) on either blog (definitely MSDN), and keep the personal stuff off MSDN blogs.
Keep the feedback coming- unless something changes, I'll probably start cross posting this week. I'm looking at w.bloggar, but if you have any other suggestions please let me know.
