I'm sick of having account here and there. Some of my peers remained at Delicious, some ran to Diigo, and I'm currently using Pinboard. I'd prefer that bookmarking sites would cooperate in some way. Not just importing data or having some sort of master-slave replication, but making inter-site social networking possible (OStatus?) and actively exchanging data. Sure, from business perspective, the data (and the user base) could be considered as assets, so site owners have no incentive in doing this. But I still have a dream...
