The Art of a Three Letter Domain Name
blog.lob.com
blog.lob.com
Even so... 'netprint.io' anyone? Would make a bit more sense than 'lob.com'. If they did actually purchase 'lob.com' from someone else, they could have cut the price they paid down to $50 or so if they found 'netprint.io' acceptable (Which is actually available at the time of writing this).
eBay?
newegg?
Apple? Granted it was originally Apple Computer, but they dropped the "Computer" from their name because it gives them flexibility to be recognized for much more than just computers.
IMO, if you want to be a run-of-the-mill company, choose a descriptive name so that you can be easily picked out of the phone book. But if you want to be an exceptional company, don't limit yourself with a restrictive name.
Unless there is something i'm missing, this seems like a really dumb domain name for this type of company.
