Phone, email, messenger, basically any collaboration software? My university assigned email addresses by initials - e.g. if you name was John Anderson Smith and you were the 167th person with the initials JAS, you'd be jas167@example.edu. Which is easier to find, search, and read in a contact list - John Smith or jas167?
