Q1) I know & I have heard it many times in WF that simple themes convert well. But again these days I see many people including some IMers buy those complex yet fancy looking WP themes and use them.
Q2) I know sales pages are long. But some sales pages are really too long and while reading them you have to literally search for the most important points.. You also skip most of the contents.... who will sit and read that 1000 mile long sales page.
So please let me ask again, do those themes convert? Just trying to know your views.
