Amazing sale. Congratulations!
The sad thing about these sales is that some guy out there that doesn't understand domaining and this sale will now spend thousands of dollars buying names like
YourDogHere
YourJunkHere
YourPhoneHere
As far as Lorem Ipsum and this domain goes, we must consider SEO. If you name your company Lorem Ipsum, and you need people to find you if they google you, you will be out of luck if all they do is type in those words. You will have to beat out those generators and the wiki page and many other sites that are pretty much impossible to beat. It is a good name if you do not care about people googling your name to find info about your company or if they will automatically include other words, like lorem ipsum construction ohio.
YourLogoHere is different. If you set up a site that lets businesses see their logo on shirts, cards, trucks, doors, and people link to it (because its a catchy name and easy to remember you are likely to get more links, like WhatIsMyIP) you have a good chance of ranking well in logo related keywords.
I think the buyer got himself a great name at a fair price and I hope his vision is a success.
