Raindrop: All-in-One Bookmark Manager
I used it for a year until maybe 12 months ago. The one thing that made me leave was that everything was juat slow enough to irritate me. Not crazy slow, but not very responsive either. When looking for a bookmark in a folder and each folder takes a couple seconds to load, then your browse becomes tedious.<p>I like that there's a good export function though, being able to be non committal to a tool is a prime feature IMO
