TalkDigger plus RSS Reading Lists plus Aggregator equals?
TalkDigger(thanks lifehacker!) sounds great! Apparently, you can use it to find all references to a given url and get them back as an RSS Feed. If you could put a link to TalkDigger’s RSS results for each of your blog’s posts into an RSS Reading List and stuff that into an aggregator, you’d have a pretty pleasant tool for logging references to your site that would make it much easier to keep track of the conversation.
