I approve of eggs for a screen name. I find the simplicity of it intriguing. Eggs. Beats the hell out of any of those cliche hotteegurl101010 or Qteegrl4567 type names. Those anger me. You can sort out all the dip****s in the world by filtering out those names alone. And for the men there are things like Sk8terwfb497. Those are lame too. If you have to replace letters with improper spelling or numbers then save us all the trouble and make your screen name DumbassXXX, where "XXX" = any number that will work.
Example:
Dumbass48202759433872837309723 "Y0 dudes, wut is goin on. I loged on aim an muh sn chnged frum BongBrotha420 to dumbass. r u getin the same prob."

Dumbass93672073927496826393298 "wut. u 2. dis sheit sucks man. isn't there no utha way too git r sns back 2 wut day wer b4 day wer chanjed 2 dis."

And the 5 people with personality can reign the internet and be easily identified by names like Eggs.
