It's just a list. Don't bother making sense of it all. It is an incomplete list.
My first focus of interest was how these sites inter-operate and connect though feeds, APIs, and widgets, in actual practice. I'm almost positive I've learned something over the last few weeks, but it is a busy marketplace and things keep shifting as I watch. You'd think these folks would take a vacation now and then.
This more technical interest of mine was in service of the Internet Marketing gods, and I discovered two types of social media sites.
- Social media sites that are inhabited, and
- Social media sites that are uninhabited.
But, what's the point of that? I already know my friends and have established reliable means of communicating with them, and I'm not talking about Facebook. Not that I would ever spam my friends beyond their level of tolerance anyway.
Syndication + social media = opportunity. It is the opportunity to smooze, make new friends, and distribute content to a wider audience. The smoozing and making friends part is critical to the success of the operation.
On the other hand IROTWS (I Read On The Web Somewhere) an offer to "Build a network of trusted friends for you!"
How the heck does that work? "Trusted friends by proxy" does not seem to compute.
