I've never latched on to bookmarking services. Don't know why - too many clicks, short attention span, who knows. But the other day I came across a new service called Gimme Bar and it's sexy as hell. Drag and drop image collecting with a pop-up for immediate tagging and categorizing. Similar to Pintrest, without the ridiculous name. Serioulsy, I hated that name so much I couldn't bring myself to use it.
Anyway. This one is still in beta, but I got my invite the day after signing up. Get some.
