I am not sure how they are going to manage the large delta between deal sizes. If they are going to make more Skype style $50MM deals then the smaller deals are just not going to 'move the needle'. In that a spectacular return on a $50k (which he cites) or even $500k deal is not going to make significant absolute returns.
That said - it's good to see they have been successful with their new fund, as the more 'right kinda VCs' in the world the better.
