Many folks are out for the holidays.
With that said, selling on forums has become more difficult for low to moderate quality domains in the past year.
The reason is lack of money; deflation ... to digress a bit, deflation is the reduction of available cash in the marketplace not necessarily the reduction in prices, though it often leads to that in many sectors, such as it seems to be doing in many parts of domaining.
Many buyers of low to moderate domains were heavily leveraged; borrowing on credit cards, home equity loans, etc to finance their domain purchases / renewals.
With cash tight, there are still many perspective buyers seeing great values, but don't have the means to buy and/or think prices will fall further.
Folks with lots of cash and in it for the longhaul are still buying - some even more.
I personally, due to some family / health issues, have been selling off much of my domains to raise cash (many buyers getting awesome deals), and plan to focus on developing the few remaining ones for the longhaul.
Bottom line is the slowdown is real, but there's still much sales activity - key is to price them right, and put much effort in advertising them in other venues too, such as paid featured listings, domain auctions, etc.
