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.

Let’s see. I’m on Twitter, Facebook, WordPress, Upcoming, Pownce, Plaxo, Yelp, MySpace, Flickr, Dopplr, and a few others.

The problem? They don’t know about each other.

Google, today, with its new Social Graph API, is trying to hook all of those together.

Another problem? If you’re a developer and build a “foograph” your new application doesn’t have anyone on it. There’s nothing lamer than a new social network that has no one on it.

Google’s new effort lets you import friends from other social networks into your new application.

The details are on the new Google Social API site (the sample apps should be turned on shortly but weren’t working when published this blog post) with more background from Brad Fitzgerald on the Google Code blog.

The problem is that for apps to be able to sense all your connections you’ll need to add (rel=”me”) tags.

Mike Arrington at TechCrunch has a few more details on this announcement.

In the test that they ran for me it showed about half of my social networks. I expect that will increase pretty rapidly as more social networking systems support the “rel=”me”” system.

UPDATE: Plaxo just shipped the first app (they claim) using this new API.

Yesterday I streamed Larry Lessig’s last talk on free culture via my cell phone. Sorry the audio is tough to hear, but it was an important speech and other recordings will eventually show up (it was professionally recorded). The Stanford Daily wrote it up. He took on the issue of copyright and corruption. Rumors are swirling that Lessig is planning on running for Congress. Lessig’s blog is here. For those who don’t know Lessig, he’s the founder and CEO of Creative Commons and as a Stanford Law Professor has launched a bunch of interesting and important initiatives there.
