I believe the expired link issue came from using a new lisp feature, but I'm curious if there is any plans to fix it?
It's a little annoying since I constantly pickup tabs that are a day old, and have to start from the beginning. Hopefully I'm not the only one on HN with that issue.
Incidentally, for those of you working on startups, this is a good example of why making something people want is not a simple matter of making what they say they want.
