Des (desparoz On The Go) has a fantastic technique for keeping track of comments you've made on blogs around the web. It involves del.icio.us tags, and it's elegant in its simplicity. I plan on starting to use this, as it will be simple with the "Popup post to Del.icio.us" link I've added to my browser toolbar. (see tip below)
Thanks for the great technique, Des!
