Lots of systems are integrating into Twitter. The Qik.com live cell phone streaming system lets me tell my Twitter followers that I’m sending live streaming video. I just hit “55″ on my phone and it automatically sends a message to Twitter.
Now Kyte.tv is doing the same thing.
Twitter could become the new presence infrastructure company if this trend continues. You might never even read Twitter but Twitter could pass messages between systems to tell various apps and services when you’re online, or when you’re available.
How does Twitter turn that into a business? That’s the $64,000 question, isn’t it?
Also, Twitter has had a lot of uptime problems lately. If they are going to be used as infrastructure by more companies their reliability has to improve.
