I've used a number of similar services; delicious, spurl and now diigo.

I've been very happy with diigo for a long time, but I feel like I'm a bit of an outlier on the service. Most users are in the education sphere, so using it to discover similar content to what I'm bookmarking isn't as good as what refind seems to surface.

Still, if anyone is looking around for something to use; diigo is worth checking out.
