Well, what's the user story that you see for delicious? Pushing bookmarks to delicious before they expire? That's the only scenario I can see being worthwhile, but as someone who swore of delicious long, long ago, I'm definitely open to ideas here!
hmm, a good point actually. Forgot you remove stories after a week.
I currently tag my delicious stories that I need to read later with "readlater" -- if I could import those direct to your site that'd be cool. Not sure if I could get thru them all in a week though!
Importing to me seems like an odd workflow though. Bookmark with delicious, import to markitforlater, read from there, links expire (or not depending on what you do), but are still hanging out in delicious. Again, the only net-positive workflow I could see would be: bookmark with markitforlater, decide you want to keep it around "permanently" so you push it to delicious. As a delicious user, does that sort of thing have any appeal to you?
