I'm slowly to realize (sorry) that the second year of FarmVille really means a new year with a deja-vu feeling to achieve level 90 (100) and get the new objects at these higher levels.
Zynga did fine job since many players were tired after level 70.
Just to pick one of the amazing things here is the overall best revenue per hour with the new three animals available for coins: the belted cow, the arapawa goat and the saddleback pig. This changes the chart in an awesome way:
After this full year of farming I had a little dip but I slowly regain energy with these cool new additions (not in the least because we finally got the Dutch flag :) )

Thank you so much for your very informative site. It is the only farmville blog that has actually given me information that I can use. Immediately after reading your blog I bought a belted cow and I am looking forward to making some money :-) I'll send you a Dutch rabbit as soon as I am on level 90 - anyday now :-)
