Good list, although I prefer del.icio.us

I always thought there is only One easy way, that is del.icio.us.

del.icio.us is not a good solution if you want to save your bookmarks and keep them private by default.
It's good only if you want to share your bookmarks with the rest of the world - which I'm sure is not what many people wish to do.
del.ici.us is a good site but it's too bad they insist on forcing you to share and don't give you the simple option to never share any of your bookmarks.

del.icio.us has private bookmarking as well, there is a checkbox.

Thanks, I did it (with Foxmarks) its great!
