If you happen to be a WordPress user, there is a plugin you should get called Sociable. The plugin “allows for easy posting by your readers to their social bookmarking site of choice via a simple set of icons,” according to the MaxPower blog.
An article on that site explains the value of using social bookmarking tools…”The primary reason to do provide social bookmarking links is exposure. Exposure translates into visits to your website which translates into prestige (whether perceived or not is up for debate) and revenue (if you sell a product or have advertisements on your site).”
The plugin includes links to social bookmarking sites like Digg, delicious (Yes, I know, I left out the dots…can never remember where to put them.), Spurl, Newsvine and others. The content of each of these sites is contributed by consumers (i.e., you and me), not “editors.” It’s part of the consumer generated media (CGM) revolution…also referred to as the “open source” movement.
If you a social bookmarking newbie, I recommend downloading “7 Things You Should Know About Social Bookmarking” (PDF).
