Thanks.

Fun fact: I've just typed a random problem into Duck and selected the first result from StackOverflow. The top answer is at 238 right now. Then I checked it in archive.org at random points at time and it seems that reputation growth was slow, but almost linear. Amazing. And I was wondering why SO posts I stumbled upon had so many upvotes, when the fresh questions and answers rarely have more than just couple of upvotes :)
