To the owners delight I must disagree with the detractors.
Simply from a technical point of view... wiki itself has already morphed into what the previous author has stated... WIki was not originally a synonym of "place to post articles". However as we do in a quick-turnaround tech culture, we now associate "wiki" with simply the articles side of wikipedia. That is good branding on their part, and bad logic on ours. I am not passing a judgment on the good or bad nature of these etymological evolutions.
Actually this name would pseudo-officially be translated as, "Chat Quick" since "quick" or "fast" is the true meaning of "wiki".
I am not trying to sound like a know-it-all. I am certainly no expert on the native language of the Hawaiian islands, but I believe I stand on solid ground in this assessment.
Now as far as what people think, that is a job for spinmeisters, and a lazy culture.when people here "wiki" do they automatically think wikipedia? Sure. But can we look at Yahoo for just a minute? To me "Yahoo" does not mean search anymore... (in part thanks to google - of which I am not a die-hard fan btw.)... But now I think of email, news, directions, people search, entertainment, and sports, all in one place. Now whether you are a fan of Yahoo or not, is between you and Alexa, but I am saying that words and brands have a tendancy to be warped in cyberspace.
Take for instance "chat". I would say that for 30 plus years, no one in America, but maybe a few proper senior citizens used the word "chat". It is an early 20th century word that was used rather often, especially in assocution with a fine, pleasant conversation. I would guess that I have said the word "chat" more in the last 3 years, than I did in the previous 30 or so.
Anyway, I hoped I have not bored people to tears, nor been over-zealous in defense of this good name.
Value? - Hard to say as usual. I own several wiki names myself and feel somewhat responsible for this latest reg craze, and posting ferver in the appraisal forum.
Undeveloped, I could see ChatWiki.com, (or literally "ChatQuick"), go in a domain store such as sedo or afternic, for mid $$$-low $$$$ to an end-user. It is short, and does use 2 popular words which can make good sense together, which is always a plus even if we don't know the niche.
I will not even begin to value it as a developed site, since I think it is nearly impossible to figure in the non-existent. Maybe I am just no good at it.
