The datadump thread was never stickied because we already had a
functionally-identical thread that had been.
People creating their own personal threads, and then getting the new ones linked in the already-existing sticky thread is a little easier for other people to navigate and work with, than searching a thread of mostly identical posts that all look alike.
Plus they allow for more extensive and in-depth content.
As for the player ABG thread, eh. If it gets more popular, maybe? I personally sort of have a thing against barfing up RL personal information on forums given that you can't shut the internet up.
