Pause for thought. Amit at Digital Inspiration likens backlinks to trackback. I had thought of them more like Technorati Cosmos, w/ no added value / increased web-presence for the sites on the list. Do the links displayed by backlinks get "tracked back" & detected by search engines, or is this purely a "who links here" sort of a thing?
Update 10/9: Improbulus weighs in with an answer and a useful dissection of the new service, esp. the "create-a-link" feature, which is the "sort-of-trackback-but-not really" part of the whole gig.
