You just got unlucky and picked the one Dynamis server that literally everyone else jumped on, I'd wager for probably the same reasons as everyone else as well.

While the worldstatus link is a useful tool, it could probably stand to be more prominent for new players on character creation.. but I can also say, as a new player, I paid zero attention to things like popularity or size. Hard to say what benefit would be had prior to players actually getting a sense of the world populations first hand.
