I tend to talk about MSN Spaces a lot which makes people think I work on that team when in truth I work with them as well as with the MSN Messenger and Hotmail folks. Although its easy to find folks who work on Spaces by simply starting from Mike Torres's blog, it isn't so straightforward for Hotmail or Messenger. Below is a short list of a few of MSN communications services folks blogs I am aware of
HOTMAIL BLOGS
MSN MESSENGER BLOGS
There are a bunch of other blogs by the folks on the various client and server teams but these four are the ones that talk most about the products they work on. In fact, if you browse the various blog rolls on their spaces and mine you'll notice that most of the MSN folks use their spaces for personal stuff not work blogging.
