How do you track comments you've left on other blogs?

Currently I'm using co.mments.com which seems to be down every other day. Highly annoying.

I was also using cocomment.com but it didn't seem to work for Blogspot blogs and I had lots of trouble leaving comments on other blogs. On top of that, it was conflicting with a website I frequent regularly. It really wasn't worth the trouble so I uninstalled it.

I'm just looking for something simple and reliable that doesn't conflict with everything else.

When you find it, let me know. I still haven't found a good solution. Sometimes I subscribe to comments if the blog offers that option.
