Dear Digg: Fix your broken login system

How many times has this happened to you: you're reading Digg, and you find a story that you would like to Digg or comment on, but you are not signed in. Digg informs you that you must login to digg or comment on stories, so you do so and... it has now lost where you were. In order to digg or comment on the story that you were interested in, you must re-find it on digg (assuming it is not on the front page). 90% of the time this happens, I simply don't digg or comment on the story becuase don't feel like wasting my time to find the story again. So Digg, please fix your half-assed login / session system- more people will vote and comment as a result.
