And at this point, it could be either or! If someone could let me know how to get the links like the StumbleUpon, Del.icio.us and Digg posts like the ones on the bottom of JohnChow.com (for example) I'd really appreciate it. Is it the DiggIt and StumbleIt plugins, or what? (I'm using wordpress). Thanks everyone!
There are several wordpress plugins for social bookmarking. Here is one (haven't used it) but you can search for others. http://wordpress.org/extend/plugins/social-bookmarking-reloaded/
Sociable is a great one, customizable with many sites included. all the info you need is here: http://www.joostdevalk.nl/wordpress/sociable/ Good luck
I'm using this plugin. It's pretty customisable and many ways to bookmark posts. You can see it at the bottom of each of my posts on my web development blog.
