Please forgive my ignorance, but can someone explain to me what social bookmarking is? Here are some of the questions I have:
1. How do readers of a blog use the social bookmarking buttons?
2. Do you have to sign up on the social bookmarking sites first before you add the social bookmarking bar to your blog?
3. On WordPress, what's the difference between Add This and Get Social?
Thanks so much. You guys are awesome.
