what does all this mean to domainers? It means that there is good news and bad news. The good news is that wiki domains are not nearly in demand as blog domains yet. However, the bad news is that wiki is not totally undiscovered either. There are still some nice word combos available but forget about buying "wiki" or wikis" in any halfway decent extension. Also, forget about registering the next BlogHosting.com because both WikiHosting.com and WikiHost.com are already taken. Although not completely accurate due to being a part of a few unrelated words, typing in "wiki" at Whois Source will yield over 1500 names that are or were taken while "blog" will yield at least 24,000 names. Like I said, that is not completely accurate but it gives you some idea of how popular blog domains are compared to wiki domains.
