Excluding Apple, I'm not entirely sure what this measures.

Twitter-ness?

it's called "social proof", instead of "Twitter-ness"

Does "social proof" generally account for gaming?

For instance, what if Microsoft chooses not to report spam accounts whilst Apple does?

It would be very much related to the rate of retweets as this is primarily how information traverses Twitter.

I think the formula is something like trendiness - honesty.
