Often when I post a comment or answer on a site I like to keep an eye out for additional responses from other people, possibly replying again if appropriate. Sometimes I'll bookmark a page for a while, other times I'll end up re-googling keywords to locate the post again. I've always thought there should be something better than my memory for keeping track of pages I care about for a few days to a week.
Does anyone any clever ideas for this type of thing? Is there a micro-delicious type of online app with a bookmarklet for very short term followup?
Update I think I should clarify. I wasn't asking about Stack Overflow specifically - on the "read/write web" in general I add comments to blog posts, respond to google group threads, etc. It's that sort of mish-mash of individual pages on random sites that I would care to keep track of for seven-to-ten days.
