it is important to note that daum is not listed here though it is probably second for volume of search. The reason is rankey is done by categories and Daum is listed as a portal site. Further, cyworld is grabbing the most eyeball nowadays and Nate . com which are also listed in other categories.
** Web search is still NOT the most popular search here. though there is feeling that Knowledge search isn't as sexy as it used to be...it still very much dominates the search scene here.
** google is very low on the search totem pole as a destination site...though they are definitely working behind the scenes and making more active advertising moves in the Korean market. (heh. google has to advertise...that's funny if you think about it--maybe they should buy a couple keywords on Overt re, who dominates the PPC market here. lol :p)
** spaces and circles are babystep copies of the "mini-hompy" models, namely cyworld and daum's planet.
** And korean portals (from what I see) still seem to dictate/lead/inspire the newest changes to yahoo (and other) portal interfaces in the US.
