The difference is that users can "digg" articles - in essence vote for them. Users can also comment on articles, and other users can "thumbs up" or "thumbs down" those comments.
Users can also "bury" articles. It doesn't change the number of votes for the article, but it does make it harder to get the article to become popular.
When articles become popular (a lot of diggs / a lot of comments / not a lot of buries) they go to the "Front Page" of digg. This is what many, many people use to get their news. People refresh the front page of Digg and check it a lot like people check Drudge - to see what's going on and what others find interesting. The goal is to get articles to the front page of digg and get the conservative message out there.
A number of us have been trying to push conservative articles to diggs front page for a long time now, but it is very hard because it is infested with libs.
If someone posts a digg link here, you click it and go to that article to vote / comment. You won't be exposed to the lib agenda articles under that scenario.
Great.
Thanks.
Will try to comply on breaks from my class administrivia.
