Ha. The snark factor of my reply might have been a bit higher than intended. Sorry about that.
About the (hypothetical) group of readers who are willing to pay for quality works, I guess it does exist. But how big it is or whether it is profitable to cater to this type of readers are way beyond me. I guess you can write a post and tag the moderators, or use some feedback function to bring it to QI's attention.
Also, if your work is contracted, you'll be promoted on the front page from time to time regardless of update frequency.
