Question

john.dot

or la la dot

etc. is it just a new fad

Answer 1

Well there you go, its just a fad. It probably just looks cool

Answer 2

Perhaps it is a anagram that means Does Own Thinking. Ya know a person who doesn't just follow the crowd however with the prevalent use of it it does seem that they are following a fad. therefore making the anagram false. Peace&Love be with you...~M~

Answer 3

Are you sure you aren't reading someone's email address?  When people post their emails online (if they don't want spam) they type them like "john at yahoo dot com".  That way an automated program can't read it as an email address.
