I just replaced the default wordpress comments by Disqus comments. Disqus enable you to track your comments add picture and other fancy staff.
I have been looking for such a plugin for a very long time (and was too foul to develop it myself).
The amazing bonus with Disqus is that you can post code! Your x<1 will be code in code, not a pseudo html tag annoying more than one of my fellow reader.
Feel free to test it on this post.
Thanks to Yas for making me discover this on : Oracle Today
I hope I will not have have to many issues with this new plugin! Feedback welcome
