Ask HN: Should usernames have a minimum length?
Some sites don't allow users to select usernames less than 5 or 6 characters in length. Is there a good reason for this?

The minimum length should be 1. Usernames with less characters pose implementation problems.
The only reason I know of is to make usernames as distinct as possible instead of user 'A' through 'Z' and then 'AB' through ZZ'. but yeah, 2 chars should be good enough. I dislike when i have to choose names like b0oooo or b0oooooooo just b/c i can't have b0o.
