The various major IM companies tend to try to create easier-to-use
APIs for developers.  These tend to have more limited functionality
than the APIs used by the official clients.  And they tend to use a
separate tier of servers which tends to be less well-maintained than
the servers used by the official clients.

>From my point of view as a third-party IM client developer: I really
wish the various major IM companies would stop trying to coddle third
party developers and just release public documentation for their IM
networks.  We're pretty smart and quite capable.  We want to use the
same, reliable IM servers as everyone else.  And we want access to the
same functionality as the official clients.  There's no need to create
a lighter-weight API or bother maintaining separate servers.

But yeah, I understand that it might be hard for a company to justify that.

To be clear... we have no problem with Yahoo employees contributing to
Pidgin.  However, you must be absolutely sure that your employer is ok
with your contribution.  Copyright could remain in your name, or
Yahoo, or IM Freedom, Inc.  The license would need to be GPL.
