To Be Fair, Social Networking Is Complicated
The first rule of flow charts is that they should be intelligible. In a presentation, you do have a chance to explain what's going on, but a good PowerPoint series makes sense on its own. The flow chart presented here is simply baffling--and the pictures don't help much. What's going where? Who's getting what? What's the difference between a one in a big black square and a one in a little red circle? What is a "follower feed"? And why are the some of the "salmon" going downstream?
Nor does this social networking slideshow rally after the incoherent flow chart: It later shows a series of e-mail screen caps that are ugly at best, and incomprehensible at worst.
