Had an idea tonight which involved the string “0wo” (zero-w-o) and was surprised to be able to hand register 0wo.org. Also note that a few in this line are still available: 7wo.org, 9po.org, etc. They’re there if you look around. Not that NLL.org are worth anything but they can be useful for URL shorteners, etc.
On a related note, I’ve owned dom.org for a very very long time and will be finally putting it use. Watch this space and I’ll tell you all about it (it involves bitcoin).
