DiKKv

DiKKv, a product of the GNAA, is a PHP script that randomly plays back quotes from three months' IRC logs of Martin "DiKKy Heartiez" Liland, the GNAA's ~~new president and current~~ Norwegian Soldier.

The script contains intelligent analysis of chat. For example, it is able to determine the "busyness" of an IRC channel. If a channel has more talking, DiKKv pastes more quotes. Interestingly enough, the quote database has been tuned to not only resemble the real DiKKy Hearties, but to pick certain quotes based on chat context to make the bot seem more real. It is very effective at making annoyed IRC netizens talk to it (usually telling it to STFU).

A popular fork of Dikkv is known as Grogv.
