Linda,

I recommend that you remember the Linear hypothesis:

CTD = Continuous Trolling Dedication

It is a valid hypothesis since it could be falsified by some sort of intelligent response by CTD.

So far it is supported by CTD's actions in 4 threads that he started and his participation in 3 other threads. I don't count the Evo-woman and Circle Boy thread because it was not about evolution, except as a joke.
