Great intro :)

There's a formula for reputation which can be found here too! In essence for every time your reputation goes up 10, it gets 9 times harder to go up the next time!

So a score of 35 is 9 times greater than 25, and 45 is 9 times greater than 35.

Reputation 25-35 is usually a couple weeks work, 35-45 will take a month or three and above 45 reputation becomes increasingly difficult to cultivate. Anyone with a reputation over 60 really has dedicated some time to their page and over 70 is a very high score indeed, usually people with lots of active followers and fans!
