I disagree with their criteria for "fake":
"Fake accounts tend to follow a lot of people but have few followers," said Rob Waller, a founder of StatusPeople. "We then combine that with a few other metrics to confirm the account is fake."I think a lot of people sign on to Twitter for the sole reason of checking out posts by politicians, stars, musicians, etc. They aren't there to speak themselves, just to read what is being posted by others. This is especially true of politicians--where people want to see what they're saying, but aren't the politician's "friend" and will not be "liked" in return. I can easily see my 80+ year old dad signing on to Twitter for the sole reason of reading a politicians' or campaigns' feeds; but he would never write a tweet of his own, would never gather a single follower, and never go looking at anyone else's feed either.
This criteria is like saying most blog readers are bogus, because they don't have blogs themselves--there is a difference between making and consuming content. You can consume, without being a producer.
