Following my off-topic comment in another thread, I would like to post it as a question now:
I always wondered, why do old regular users with high reputation use names like user370305 ?
What's your thoughts about it? Maybe we should gently ask experienced users (after they reach some reputation value or after a certain amount of activity time) to change autogenerated names to something more meaningful?
p.s.: pls note, that I read Why do some users have username "user########"?. But I ask a different question here.
