Topsy just sent out this message over Twitter: "You can add any site (including your own) to Topsy's index by tweeting it attention of @topsy. We'll include it within a minute. #topsytips"
What does it mean to add a site to Topsy's index? I thought that Topsy was ranking links, based on how they're included in tweets. Could this possibly mean that they're going to sent a robot to index the submitted web site? If so, for what purpose?
