as an undeveloped domain, i dont think it could be sold for more than the cost of registration.
think of what the word "dizzy" conjures up, head spinning, about to collapse, not exactly the type of image you would want to associate with web hosting.
Hostjet i agree, thats why i wasnt sure whether to buy it but it can also be translated as dizzy hosting at dizzy prices, i posted about it in the lounge and they talked me into it lol.
I have got a good rep with my other company so i am hoping to develop this into a good company too.
You just have to find the right angle and it could work. Think of the things that make you dizzy... spinning, speed, etc. If you play on the speed aspect, something like a phrase under the URL in the header of:
"Speeds so fast... <insert clever last part>"
Association could make it work. Obviously if you associate it with having too many drinks (read: bed spins, heh), then you've got problems. I think you can make it work if you get creative.
