Writing about web page http://www.spurl.net
As a contractor I consider my bookmarks as invaluable, however I face the constant problem of having to maintain this list of bookmarks on my works computer, my laptop, my home computer etc.
Enter spurl.net, the online book mark manager. It is free, requires only a username/password (no email!) and has excellent integration for both IE and firefox (and probably others). Rather than using the browsers bookmarking facility, I just use spurls.
When I spurl, I have the option of entering a number of tags which I can use to retrieve the link later. I can also put the bookmark in a traditional folder hierarchy if I wish.
One of the added benefits of this is that for any given bookmark, I can see a list of bookmarks that other users have assigned the same tag to! They have used this "tag searching" to create a search engine; zniff.com. Think of it like a human edited google ;)
One of the other invaluable features is that you expose your bookmarks to anyone. Quite often I am asked to leave a copy of my bookmarks when I leave a position to aid the junior developers, well with spurl that is simple.

There are also RSS feeds available for most things.
