It's great that so many people could become members!
Your post made me realize that trying to get a sense of the revenue made from memberships is probably more complex given that YouTube's pricing is not quite accurate with current exchange rates for some countries. E.g. It's $9.99 USD if you're in the US, but 1190 yen if you're in Japan (which is ~$7.96 USD...the yen is weak to the US dollar right now). Depending on the countries where fans buying memberships are located, YouTube may be charging more or less than the equivalent of $9.99 USD. And of course, subtract 30% from that for YouTube's cut.
Just some food for thought :) Ever since Yuzuru mentioned introducing YouTube membership I started becoming more curious about the specifics and tried to look more into it (along with the topic of taxation in Japan).
