My uptick also started in November. GoDaddy and Sedo primarily, but just had my first sale at Dynadot. Beware of selling through Dynadot, they don't have a payout option, you have to use the payment as account credit (crazy right?). But, it was a small sale and I have a lot of renewals coming up, so no bother for me.
If you don't have your GoDaddy names listed as "premium" listings, you should - keep in mind they hit you for 30% though, so price it in.
