think of it this way: AGQ traffic the past few weeks has been something between a tenth to a hundredth of what is was before the bungee jump in May; ditto for SLV. don't know about PSLV.
the failure of Yahoo to explain this publicly is utterly disgraceful and in my opinion tantamount to a breach of basic human rights. this is not the behavior of a responsible, moral and ethical company. they need to explain. while in principle we use their board at their expense, we can equally argue, it is our postings that make Yahoo finance as important as it is. though your individual post does not directly result in revenue, indirectly, it creates traffic, which can create revenue for the company. Yahoo has assumed a responsibility that it is failing to uphold and quite frankly such behavior borders on totalitarian abuse. I see them in breach of contract.
