I've decided to try out DISQUS for handling comments on my blog. Let me know what you think. I can always revert back to Blogger comments if desired.
Update: It turns out that there's a bug in Blogger that precludes you from using DISQUS in conjunction with an external post editor. Since I'm happy with Windows Live Writer, I guess I'll disable DISQUS for the time being and revisit the decision if the bug gets fixed.
