How about a way to follow the comments you make on other people's blogs? With so many new sign-ups to Sweat365, I only make the occasional comment on newbie's "Hi I just joined" posts. But those comments tend to be because something in what they've said in their initial post has really caught my eye.
It would be nice to be able to have an easy way to follow those blogs, but without adding them to iGoogle / blogroll / bookmarks as I don't want to create another housekeeping problem on my PC. I think the generic Wordpress blog has this feature, and if so, is it just a matter of flicking the switch on Sweat365?
