The shorter a domain name is the better.
When that domain name is being used for mobile content ie. for stuff you’re accessing from your mobile phone or other handheld device, the shorter URL will always win out.
I mentioned that dotMobi were planning on releasing one and two character domains some time ago, but it’s only in the last couple of days that they have published more information on the process.
Unlike some registries that auction of the really high value domains, dotMobi has been using both auctions and tenders to assign domains. So this time round it will be a tender / proposal based system again.
And the cost?
Well apart from a handling fee of a few hundred euro it won’t actually cost you anything.
