SIMPY, SHADOWS and DEL.ICIO.US all do this wrong I think
I'm curious why social bookmarking services like Simpy, Shadows, and del.icio.us prioritize a user's tags over a global view. When clicking a tag, I'd rather see globally relevant tagged pages than just those from a single user. A single user's tagging habits aren't as useful as seeing the broader community's perspective on a topic. Ideally, these services would offer a toggle between user-specific and global tag views.
