Not a fair reply, Zynga today makes >90% of its revenues from virtual goods (and above 80% of that is from Farm-ville) that was not the case when Fred invested when they were makeing >75% of their revenues came from offers.
where do you get this data? it is wrong. nowhere near 80% of zynga's revenues come from farmville. i won't say more than that because it is nobody's business. but it is not even close to 80%.
