Cryptic's Dan Stahl refers to a lack of popularity for Klingons as an excuse not to develop content for the faction. Cryptic also refers to PWE and CBS as coming to the same conclusion.
The following puts their claims to shame with cold hard numbers (as of May, 2012):
"Starfleet" on Google: 5,350,000 results
"Klingon" on Google: 56,100,000 results !!!
Keep in mind that you could never start a Klingon character in this game fresh from level 1. You had to "unlock" it by playing on Starfleet first (yuck!). This is how it was sold to their customers -- on a false promise.

I would have posted this on the official forums but I don't play this scam. Still, I'd like to warn potential customers about it before they waste their money on its Cash Shop, which, by the way, existed since release.
Bonus Google search for a phrase "content drought" shows STO related article about the lack of content as a first result, despite the words in the phrase not being unique to STO.
Also, looking at the forum activity here, it doesn't look like the game is doing well at all. :cool:
