Google don't want you to use bookmarks, which is why Google Chrome bookmarking sucks.

There's definitely a niche in the market for a bookmarking site that does some form of bulk importing of your bookmarks; has really easy organisation (drag and drop, and an API for power users); has some kind of thumb-nail; has some kind of link to Internet Archive (to read old sites); and maybe a link to IA to store sites. The internet archive stuff could be a paid option with some money going to IA to help fund them.
