We have a certain number of users of the site who have been here for some time, but still retain their original username of the form userXXXX. I find it relatively annoying as I'm never sure whether I've interacted with them or not, so they all sort of blend into a single user. I wanted to test how much of a thing this is, and the resulting query,
took me a bit by surprise. There are 18 userXXXXs with 1k rep or more, generally with over a year on the site, and they total between them almost 50k rep. At the lower bar of 300 rep there's over 60 such users.
To users with such usernames: please consider changing your username to something more distinctive. If nothing else, it will make it easier for other users to interact with you.
To the rest of the community: are these numbers bigger than we'd like? If so, how can we encourage people away from this?
