I used to have it on my personal blog. Now, I don't because my weblog isn't just a personal anymore.

I also decided to stop using it because it was redundant to the existing comment system in blog publishing engines. Not to mention it's a waste of space without any real good use.

My advice, if you want to chat online. Build a new page and incorporate the box there on its own or maybe turn that into your small 'IRC' space.
