Social bookmarking/news links are extremely popular these days. There are a ton of different websites out there, from the Digg.com's to del.icio.us and furl. I personally only really use del.icio.us, but whatever your choice, you can be sure that you will have visitors that use at least one of the different services.

Enter the social bookmarking links. You've seen them, the Digg This and +delicious links that seem to be on every page, everywhere across the entire internet. (yes, they are on this page too).

Adding these links to your wordpress blog couldn't be easier. There's a full-featured button creator on the TwisterMc page that you can use:

Or if you want to have the icons similar to the ones you see at the bottom of this post, there's another plugin called Social Bookmarks Bar that I prefer, mostly cause I want a less intrusive link.
