I noticed that lots of new users neglect to choose a display name, and they appear as something unreadable like user98765. Many of these users are registered and do sign their questions at the bottom, but they don't set their display name.
Should we and can we do anything about this situation?
I guess it must be due to how the SE signup process works at the moment (which most of us won't be familiar with as we signed up a long time ago).
