Couple ideas to add:

1) Being able to share links to a group of people. Often i'll share links with coworkers, and it'd be nice to have a record.

2) Custom lists. So I can make shareable lists of related links.

Yeah, definitely look more into unifying and integrating facebook and twitter.

Great ideas - added them to our ideas document. Building out these sort of specific features around link sharing is how we are going to differentiate ourselves from FB, Digg, etc.
