Samsam... keeps posting that there will be 2.5 billion restricted shares coming to the market between March and September, so I crunched the number to show that it was just not possible.  You are exactly correct in that the point is that almost all of the selling has been done and that the probability that the 804.5 million shares are dumped is low, especially since most are held by insiders.

In short, nothing to worry about.
