the first thing i will teach them is to think of good, catchy but not too overly pa-‘cute’ username
so they will not end up like me who is stuck forever with owrange
from somewhere in the www i read that username is somehow like your brand
so get something catchy but not as dumb-sounding as owrange
for example when presenting to some prospect client: yes, i’m a 3rd-world serious blogger
you can verify it via my website, owrange.com
there goes your popularity/credibility rate
what are you — big sister of myspace and the friendster of friendster?
but at the end of the day, do not judge a user by its username.
