A friend read my rant about Delicious 2.0 and knew someone on the team. He shot them my post and this was the response:
"They think you have a good point about the breadcrumbs are thinking about a better way to do it."
Kudos to them. If I had more time I would jump in and help, but as it is the next iteration of Socialcast has me up to the elbows at the moment.
I do hope some good comes of that post. However, until then (or maybe never) I have resorted to importing my Delicious feeds into Google Reader.
