Blog tracking and commenting services such as the now Yahoo owned MyBlogLog continue to have fairly widespread usage, but using these services could pose a security risk, at least according to Citibank.

Zoli Erdos uses both MyBlogLog and BlogRovr and got a rather interesting message whilst trying to log into Citibank:

Could something you type into a secured site on Citibank end up on one of these services? If it’s a browser plugin that sends data back to a central service it could in theory track and record anything…although that presumes that these services would also be being used for evil as well, not just for occasional spamming like some services are.
