They've posted this sign all over the Seoul subway system. I took the following photo about a week ago and the large letters say "everyday".
Checking out the website link shown produces this page, which says under the logo, "There is good fortune for those who wait" and then "from office workers, for office workers, by office workers" and D-15 indicates that there are 15 days remaining until this great new service is announced.
Obviously they are trying to generate some viral marketing, so I'm doing my part in getting the word out. However, considering how many millions of people are walking past these signs on a daily basis and that only 6,755 people had visited as of today (about 5,000 had visited when I checked 3-4 days ago), I'm not sure if they're doing too well with the marketing.
