It would be trivial to implement a Bookmarklet that works in Firefox (or h*ck I bet you could even implement one that would work on both!), so why didn't the MSN Spaces team do this?

From A comment on Carnage4Life's Space: What Blog Posting APIs are supported by MSN Spaces?.:

While this does not represent our API strategy, we have implemented a basic HTTP URL based "API" that we use for the Blog It functionality (IE only). While this serves a different purpose than the APIs Dare is discussing, this URL can be used to pre-populate the on-line blog entry forms. The details can be found by following my blog url above (as well as an "experimental" IE toolbar button for quickly blogging on-line articles).
