How will this affect links for third party services that clients handle natively, such as Twitpic (and obviously TwitLonger, which already has shorter dedicated short urls for its posts)?
I'll also be interested to see how this goes down with the privacy types who will now be paranoid that Twitter is tracking the sites they're going to, even if they are going through a third party client. If I'm clicking a link on a desktop client, should Twitter really be getting that information? What about links through bit.ly etc? Will I still be able to see the analytics that they provide for my links? If so, does that mean there will be at least two levels of redirection from the ultimate destination?
