The LLLL.nets you came up with are sure worth something. Would love to have hate.net for example.
I have faith in short, good, generic domains. Preferably .com of course. Read somewhere that the use of mobile Internet, in its cradle at the moment, will demand shorter and easier to type domain names. Some part of me agree with that.
Maybe the current LLLL.com wildfire will spread over to LLLL.net as well? I went ahead and regged a .net yesterday, took Ocka.net, name for "a uncultivated male" in Australia .
But .net will always be the unknown cousin of king .com.
Of course this kind of names have substantial value, as for all the other dictionary words .net
The fact that they are so short is also an addedd value. Unfortunately, most of the pronunciable llll.net (and almost all cvcv.net) are taken, so meaningful 4 letter .net are not an easy find. If you have found any for regfee, I'd say go for it.
