Mister Wong

Mister Wong was one of the largest European free social bookmarking web services.
History.
The website was a German startup, established in 2006. Kai Tietjen had been running an ad agency for nearly a decade, when, in March 2006, he entered the field of web entrepreneurship with the idea to "take on Google". Investing mostly his own money, he created a website that allows customers to bookmark their favorite sites, and then uses those bookmarks as the basic data for its search engine : to find a popular site, a user can search all other users' bookmarks. The service ceased operation after being sold for €2500 in October 2016. 
The service was available in German, English, Russian, Chinese, Spanish and French.
Origin of name.
The website extols its users to "Wong the Web!", a reference to the practice of Wonging, often employed by card counters in Blackjack.
Controversy.
Mister Wong's original logo, depicting a "cartoonish, nerdy East Asian man", brought on protests from many Asian-Americans. The website's creator subsequently issued an apology and removed the logo.
