I have numerous mobi, I have some developed sites.
What I am about to say I am sure will piss some folks off.
Flowers.mobi was not a $200,000.00 domain when you compare it to something like maps.mobi or stocks.mobi or invest.mobi.
RealEstate.mobi is not an $85,000.00 domain as perhaps Realtor.mobi or Agent.mobi would be.
But, obviously they were worth that much to someone and all I can say is good luck just as I am sure they are saying what the hell do I know.
MLS.mobi would be a worthwhile catch and could potentially be a highly searched site. Keyword..."site".
Flowers.mobi could be a highly searched "site".
theMLS.mobi? not worth more than reg fee as a domain name but as a site could be a highly searched site.
