Rebrickable actually turned 2 years old last month, and I completely forgot about it :) The site has continued to grow and has had many great changes made in the last year.
This image is a shot of my analytics page for those interested in this stuff.
The StatsThere's not much I want to say, so will just pull out a few stats. The last year has seen about a 2.5x growth in user activity compared to the first year.
A big factor of this growth was the integration with Brickset, so thanks Huw!
