Traackr sounded cool to me. That was based on the assumption that it would actually track things. But it doesn’t track some of the web services I use.
It claims to track Flickr, but a couple of days after I told it about my Flickr account, it still claims that I have no content. Maybe it saw images (and potential profile photos) like this one, and got scared off. I’m not sure I blame it, but I think that I am now scared off Traackr, and inclined to look at some of its 30+ competitors.
