I saw a blog post by a member of dnforum/namepros who did a survey of 100 random LLLL.coms and found out 24 were websites. Here’s his blog post:

NNNNNdomains.com

So, i thought i would do similar test and see what results I come up with. I only took 33 LLLL.coms randomly and here is what I found:

33% were developed websites. Most of the rest were parked domains or forwarded domains.

Here’s the list I chose. By the way, my method was fairly unscientific: I just took a dictionary, a pencil, closed my eyes and put the pencil down on the pages. Where the pencil landed was the letter.

agcn.com website for a business with words that fit AGCN
