I’m still trying to suss out a reliable, CMS independent way of tracking the comments I’ve made. It’s a step back in terms of automation, but using a Delicious tag seems functional at least – and it lends itself a quick and dirty Bookmarklet too.
I’ve not integrated any feeds into the site yet, and won’t have time to for a little bit, but if you want to see what’s got me talking, you can find it tagged with @commented-on.
Edit: The bookmarklet I speak of is a simple modification of the standard Delicious “Add to Delcious” affair, and looks like this:
javascript:location.href='http://del.icio.us/USERNAME?v=3&url='
+ encodeURIComponent(location.href)
+ '&title='+encodeURIComponent(document.title)
+ '&tags=@commented-on'
