Totally agree..
(1) Not really keywords or "brandable"
(2) Don't remember that last time I seen
a (dot)me/space receiving any bids at a auction
(3) Because of the really low price to register (dot)XYZ recently..been seeing tons dropped..
(4) If they were mine..I would be happy to receive low XX for them..but most likely I would let them expire! The only other option that I would have, would be to develope them and hopefully find the right buyer!
