Create an IM Protocol?
Recently, I have been thinking about creating my own IM protocol. Mainly due to the fact that I think there should be another alternative in a lightweight client that supports every OS (using Java).
However, I think this wouldn’t be that worth of a write. This is because there are already written alternatives out there. For example, there’s XMPP (or Jabber), Skype, and Google Talk (Jabber). Yet, people do not use these are much. This could possibly be that they are not as popular as AIM or MSN. Also, there is already alternative clients that support multiple protocols, such as Pidgin (no ads), and Disgby.
