I think user names should be used like a genre on this site... you know how tons of them are used by different people ie. "Joe" will have lots of different contributors. Often posters fill in a name related to their definition, so clicking on a certain user name, one could look at certain categories! like, "cynic", or "nonsense", or "patriot", or "nihilist". that'd be cool. just a random thought...

Jesus Christ, there are far too many here to mention.

All of you assholes should find a new hobby.

A user name is used on sites where people post messages. I find the user name tends to cause a state of chaos. On some sites there are photographs as well as a user name causing total chaos. I jump to irrational conclusions when two people look alike - " Are they role playing ? " I wonder.
My user name is shown below.
