wykop.pl is a Polish social networking internet service, originally founded on December 25, 2005. It is modeled after the American website digg.com (wykop in Polish language means unearth! or dig out!), it's also very similar to reddit.com. The basic idea behind wykop.pl is the collection of potentially interesting internet-based information and making them available to users. The server is managed by the Poznań company "Wykop sp. z o.o.".
ReadWriteWeb described wykop as a "clone" of Digg. As of 2006, Sebastian Kwiecień, owner of the blog web20.pl, said that it was probably Poland's most popular Web 2.0 website.
Other part of service is a microblog based on hashtag system, which can be subscribed.
Nicknames of users have different colors. After registration user's nick has green color, which after 30 days changes into orange color. Special colors are: claret for 1,000 users from the top of user ranking, blue for the sponsored users, black for the admins and silver for the banned users and users, which deleted their accounts.
