आर्डवार्क (en. Aardvark)

Users could also review question and answer history and other settings on the Aardvark website.

The park is known for its large mammals, including aardvark, baboon, African buffalo, caracal, cheetah, African bush elephant, hippopotamus, African leopard, West African lion, serval and warthog.

Aardvark was released to the public in March 2009, although initially new users had to be invited by existing users.

A secondary flow of answering questions was more similar to traditional bulletin-board style interactions: a user sent a message to Aardvark or visited the "Answering" tab of the website, Aardvark showed the user a recent question from the user's network which had not yet been answered and which was related to the user's profile topics.

During the study, eight of the radio-tracked pythons laid eggs in aardvark burrows, and Alexander recorded their breeding behaviour using infrared video cameras carefully lowered into the nest chambers.

In all of the interfaces, wrappers around messages from another user included information about the user to facilitate trust: the user's real name, age, gender, the social connection between the two users, a section of topics the user had expertise in, and summary statistics of the user's activity on Aardvark.
