It's important for the capability to be there. The issue is that currently "established players" control that experience. In a saner world, experience needs to be decoupled from infrastructure.
Somehow, ICQ worked wonderfully despite everyone I knew using an unofficial client. The official client (at least Windows one) was a terrible mess. It had ads and all those features no one ever asked for, like games and and news and an entire picture-based language (I'm not joking). But QIP, the client I used, only did the things I needed an ICQ client to do, and nothing more. It also had no ads.
