Up until now I really haven't looked into social media much. I've been flat out blogging, writing articles, and basically making a living in my "real" job. But lately, I have finally started getting into social media. I can now really see the benefits.
One tool that is a great way to get into it is Add This. It's basically a button that you can add to your blogs, sites and posts which facilitates their addition to a whole host of social bookmarking, networking, blogging and micro-blogging sites. (You can see the button below and also in the right panel.)
Apart from anything else, just the list of these sites on Add This is a great resource. There are hundreds of them! This aspect of internet promotion is fascinating, and I regret having neglected it for so long.
