Which do you consider better as a URL for your blog post:
http://blogs.imeta.co.uk/dgray/archive/2008/10/01/409.aspx
or
http://blogs.imeta.co.uk/dgray/archive/2008/10/10/preventing-tfs-from-creating-work-items-when-a-build-fails.aspx
I know which I prefer, and I'm sure that search engines will give you a better ranking for the later. To set this up under Subtext (we're using version 1.9.5.177) simply go to the Options Tab, then under Preferences find the "Auto-Generate Friendly URL" checkbox. All future posts will come out with a much friendlier URL.
