My two cents: make "seeks" into separate threads you can drop/save and continue at any time. Also the ability to sort and delete these hypothetical individual search nodes would be nice. Automatic forwarding to a previous thread of another user containing the term I was searching for would be intuitive, so that users don't have to pioneer search histories already made. You could even "adopt" a thread and pioneer it further for the community. The opportunities for education are endless: students can share their research threads for use by others to include in their own bibliographies and sources (somewhat perpetuating the inbreeding of stale thought in academia but convenient for aggregating it in one place and possibly a starting point for defying it). You can make a dating app to analyze users' data and make compatibility suggestions where there is statistically significant commonality. Also, take a look at http://www.pearltrees.com/ and learn from them. People aren't neat freaks, take advantage of all that is the "lifestream." You guys may have some of what was said in the works but personally I think the dating idea might be most ripe for pursuing in the future. The site as of now has merit to the social bookmarking crowd I think but needs to stretch into new territories that utilize the all important search history for focused applications. Last, don't listen to the nay sayers who insist on you spoon feeding them, it's a waste of your precious time. Best of luck.
