1. that's what the incentives/points are for. attacting QUALITY and in dept answers. people here right just as long and indepth responses to Knowledge search (aka Answers) as they do on forums. its even "status"/internet creditbility thing for many.
2. Cart before the horse. They've already succeeded in many ways if it the situation you describe comes about. That is, people will look to Yahoo Answers FIRST to get whatever results or information...and THEN if they still need more in detail (as you said) will go elsewhere. Peoples responses (if quality) is almost always better than a bot. (Such is the case here.)
Naver KS is the DEFAULT search cause in the end...humans will always be more accurate than a bot, ESPECIALLY for information search that not just a web site (ie: looking for a specific company's web site...which a crawler can do better with from what I've seen in Korea).
as I said, in my other post joking...I'll say again more seariously...
this can be a real threat, or at least, have a very affect on independent forums and community sites. By no means is it a replacement, as it is not in korea as well, but its naive to think it won't have its long-reaching consequences to sites, even WebmasterWorld.
eg: if search for "web master tips for optimizing my site" I will proably come up with plenty of WebmasterWorld threads.
cool. But if down the road, many people search at Answers first (which they will - ex, if yahoo makes it the default or second tab search engine cause it has "enough data"), it comes directly up with a detailed reply (rated highly by other members) and perhaps a couple more replies saying "check out WebMasterWorld.com as well for more in depth replies".
some people won't go an further than that. some people will check out the link to WebmasterWorld. but already you are losing people that normally would have comee here directly.
this is just a SMALL example of how it works here.
KS or answers, is unmatched for getting access to TACIT knowledge. period. because its people. dmoz is a pale pale pale comparison. Once that hits critical mass, its going to be tough to get to beat or dislodge from the market (unless some paradigm shift happens in search---like mindreading or true natural language whatever. lol).
again, web search is still useful and great for many things(in Kroea) but there is a reason KS is first and web search ofen the 7th or lower in useage in the types of search here. its just better.
I'm very excited for seeing this become a reality....and very bummed at how this takes a lot of the steam outta my sails for things I've been doign for my small communities. lol.
it comes down the people....if they ask good questions and reply well (like they do around here), it WILL be the next search revolution. I guess we just ahve to wait and see how well the US market takes to the payment/points system.
let's just say though....I'm buying considering buying some yahoo stock over GOOG for the first time in years.
