I started way back with suffusion. Found it a bit daunting at first even tried a number of other themes including Atahualpa but something kept bringing me back to suffusion and the forever happy cheerful and hard working Sayontan Sinh hope he makes a lot of money from this he well deserves it. If you are looking for the best free theme around this is it. Bit hard at first but stick with it as there is nothing out there to touch it.
Keep up the good work :)
As for WordPress development team giving him a hard time !! Wake up guys smell the coffee
