It’s taken a while for me to notice, but I don’t get any messages from Twitter any more. I no longer receive SMS notifications, or IM notifications, or anything else for that matter. I just don’t get updates. I’ll probably have to start reading twitter via RSS. Bah.

Apparently this is old news.

I wonder how it will affect Twitter’s business. They’re so popular the system can’t cope. Yet they still haven’t shown a clear revenue model. Who’s crazy enough to be paying for the whole thing? It all sounds very .com bubble to me.
