Though WLW is not cross-platform, it is one good "free" software from MS. And if you ever want to blog or share info, this application allows you to post any content type to most blogs.
A friend of mine has been looking at a few solutions to centralize and share his code w/ his team. Out of the box, WLW supports quite a few blogging solutions. Of course the first and preferred options are Windows Live Space or Sharepoint, but it does support quite a few more. Including the leading Free and Open Source ones (drupal, wordpress, etc.).

However, what you might not know is that WLW is quite extensible by the use of plug-ins.

With that in mind, there exists a vast amount of them available that will enhance your blogging experience and make your life easier.
The first link in the list below is for my friend (CT) to check out some of the nice plug-ins available to address some of his needs (including for example the code syntax highlighter)
