This question already has an answer here:
Some SE Philosophy users are using numbers for their user name. It is difficult to identify them. Now the number has become a 7 digit number [e.g. user1234567]. So, isn't it good if they use some names instead of a 7 digit number?
We can't distinguish user1234567 from user1235467 and remember them quickly.
Is there any logical alternative for selecting username by default to solve this issue?
