I have a large number of bookmarked sites and links that I want to be able to access on other computers that I use. Is there a way for me to share or access these without having to sync them by hand?
You might want to try Delicious. They do have a firefox plugin that allows you to sync automatically between the website and your browser if you wish. And you can save your bookmarks in delicious rather than the browser bookmarks if you prefer. They have tools for importing/exporting bookmarks from your browser when you first set up. Plus you have the added advantage of being able to access your bookmarks even if you are not on your personal machine(s). Delicious does allow you to keep your bookmarks private if you wish.
The only downside is that you will be organizing bookmarks by Tag rather than directory as you would normally, but personally I found I got used to that pretty quickly.
If you are a Firefox user, you can use Firefox Sync, it will automatically keep all of your bookmarks in sync between any of your Firefox browsers, even the newest Firefox mobile browser.
