What are those colorful icons at the bottom of each article?
Social bookmarks. They're fun.
Using this site
These things? 
They’re bookmarking links to various social bookmarking sites.
Clicking those icons will post the current article that you’re visiting to the bookmarking site that you selected (the one you clicked on).
Social bookmarking sites are sites like digg, blinklist, del.icio.us, kinja, technorati, etc. Basically a centralized place online to store and share (if you want) your links.
If there’s a social bookmarking site you use for which there is no icon on this site, and you would like to see it added, let us know.
