Because User has a classic tendency to become a God Object. :-)

Brandon, sorry if I'm repeating stuff that came earlier, I didn't pay
much attention to this thread until the above exchange caught my eye.

The User class tends to accumulate a lot of crud (not to be confused
with CRUD), becoming what we call a God Object, one that sees, knows,
and tells all.

To combat that tendency, remember the Single Responsibility Principle,
and look for clear dividing lines to separate responsibilities. What
I usually do is keep User responsible only for logging in and out, so
it usually contains only username, encrypted password, and (only for
purposes of sending password reset tokens and suchlike) an email
address. Any other personal info, like a "real" name, address, phone
number, biography, picture, etc. goes in a Profile object that
belongs_to that User. Other info for specific aspects of using the
system, like availability and desired salary if it's a job board, go
in more specific profiles, like JobSeekerProfile or JobPosterProfile.
