I have been wanting to write a comparsion of existing social bookmark managers for a while. Someone called Kossatsch has done it for me. He did a much more thorough job than I would have. Here is the PDF.
I’ve also been playing with the recently released mysearch.yahoo.com and A9’s bookmark feature. I like MySearch – but it is still missing the social aspect.
And now myweb.yahoo.com is inching closer to the goal.
