I learned from the docs here at http://slashdot.org/ that all users can be moderators, in fact its automatic. (link lost due to bad karma)
So I lurked around waiting for an opportune moment to use my 5 mod points.
Days past, then I made a comment http://slashdot.org/comments.pl?sid=118508&cid=10010865 and get modded down. I get bad karma, I get my mod points taken away.
The moral of this story: Don't make religious comments, hell dont make any comments, and you get to mod other ppl's comments down or up. Thats what I call interaction.
