I find this to be particularly concerning from a privacy point of view. You can retrieve enough information about a user to even replicate their home page. This could be particularly damaging from a phishing point of view. Not only can I spoof the Twitter home page, I can now spoof the

Well and generously spoken, Damon. I coded up a proof-of-concept site for this leak today. It works so well it's scary. I am now quite hesitant to release the address publicly because of the backlash I might receive for deceiving people by sending them there. I may be willing to share it with

Actually, I see this functionality as a potential security/privacy hole. I can imagine at least a couple of nefarious things websites can do by being able to detect the presence of a twitter user on their site... I remember bringing up a very similar issue with Alex earlier last year which was

We did an experiment with a partner of ours around this. It's not currently an officially-supported API method, but check out /sessions/present.json. It should support a callback and returns a boolean. On Mon, Jan 5, 2009 at 07:49, Chris Heilmann chris.heilm...@gmail.com wrote: I've just
