I find it funny that most 4channers have no clue that tripfags post as Anonymous all the time. Currently, I'm willing to bet that something like 80% of all my posts are Anonymous. A couple of months ago, about 70% of my posts had a trip, but not now.
Having an identity is funny and even useful in some cases, but if I wanted to post with a name all the time, why the fuck would I come here? The best thing about 4chan is that you can just clear your name field and you're just another face in the crowd.
