We plan to add RSS exporting as well as a few other features, but mostly what we're going to try to do is figure out ways to mine bookmarks for stories. You can best help by tagging bookmarks on the global bookmarks pages. This is all very experimental, so your help is appreciated.
Now as always on Slashdot we appreciate your feedback and bug reports. You can do this the slashdot SF project page. Or even better you could visit the site and consider submitting patches. Ideas are never in short supply here- time to code them all ALWAYS is. Join the mailing list! Or just start bookmarking and tagging stuff. Lastly, thanks to Tim Vroom who put all of this together.
update to clarify a point for the readers- this system is primarily an extension of our submission bin. You are welcome to bookmark & tag for your own pleasure, but our intent is that this system eventually be used to help us find content for the mainpage. So of course the functionality has overlap with other sites. No huge shock there. But our intentions is to use user bookmarks & tags as another input channel for editors picking stories for the audience.
