So, in my continuing attempts to sell some of my domain names, I've tried three new (and completely unsuccessful) approaches:
1. Giving away domain names in return for someone giving me the one true sales solution. (Two people did give interesting replies -- essentially suggesting that I manually try to sell the domains to end users.) However, neither expert was interested in the domains I was giving away. (Thanks Andy, though, for your kind words.)
2. I tried selling Bridal-Fairs.com on DigitalPoint's Buy/Sell/Trade forum. No nibbles, even at the bargain basement price of $8.
3. I approached Rick Latona about selling WoodFurnaces.net and WoodBoilers.net. He politely declined -- though whether it was because he didn't like the names, or because he thought my price was too high, I'm not sure.
Which leaves me, perhaps, slightly wiser and slightly disappointed. Next up: contacting end users.
