I have the same thought. Heck, voice and video chat, file sharing, even primitive forms of 'integrations' (in the form of IRC bots and the like) have been around for many years at this point. I remember the Yahoo messengers and the MSN messengers of yore having a majority of the features that I see in the modern chat clients. It really perplexes me that these new chat services are apparently worth so much money. Yes, you took some trends and put everything into a convenient package. Is that alone worth billions of dollars? The actual technical innovation is minimal.
