Approximately 100 gems, representing about a third of downloads.
The original plan was to target based on download rankings, but these fluctuate, so in theory gems could be added and then removed from the list. A count of downloads can only go up.

This seems to be like it would mitigate the on/off problem of using a variable metric while also being biased to the currently relevant gems/users.
