>>14 Hay, not all the TT crapflood modules use Markov chains; some do (using various sets of input texts) but some use the fortune program, either using the standard unix fortune files, or several custom files such as a database of real TT post subjects from the Trolltalk Archive (RIP). One module uses neither Markov nor Fortune.
And the Markov is a custom implementation in Ruby; pretty basic, but whatevs.
