I recently converted all my bookmarks to saved copies of the pages in Evernote. This means I have full text search over everything I "bookmark" -- still have the links -- and never lose it regardless of what happens.

In this process, I was shocked at the number of 404s I encountered from relatively recent (last 18 months) bookmarks.

Evernote is a bit of a wreck, but so far the combination of decent copy of page, browser plugins, tags, search, accessibility (phone clients, web client, some native clients) have made it my best option.
