There's a lot of fear out there, and LLLLs are speculative (unless they happen to match an existing usage - The Engineering Society of Buffalo is not a great prospect).
There's no telling when the market will turn up again, so speculation is not very attractive. At least with a keyword domain, you can set up a mini site and make a little money off it.
I think this year will be another rough one, and prices will fall more on these types of names. There will be some good buying opportunities, but only if you can wait a while to see a return...imho.
For me, the question is: do I want to tie up my money in non-performing names in the hope of future returns? Considering the economy, I want my money working for me and available.
