Funny you should mention minutes, I was also thinking of a way they could sell subscriptions by minutes used, for instance, someone with only a short drive time may opt to only pay for the minutes used. Though that could be a big money loser since we already know that people would certainly love to choose the only 2 cable channels or so they tend to watch. who knows, some more thought on that one required.
The only insider sell that is acceptable to me is the ones with some odd shares are sold to pay the taxes on share income or whatnot.
But, knowing the company is growing and all the new deals with used cars, 2.0, higher rates being accepted and in my opinion a still little known service (i know its been around a long time but I think people stlll don't understand what that radio in their car is capable of entertaining) I don't see the sells as rats leaving a sinking ship, that doesn't make sense knowing the potential here. unless of course they see something like royalty rates eating at revenue or such, which, of course, only insiders know, so thats scary.
I have recently met 2 50/60 year olds at work that listen online, and that surprised me because I never suspected these 2 particular people as satrad fans and one of them cant get enough of the political debates on whatever he listens too, and he shares his enthusiasm for it . To me this shows potential of fans creating new fans, similar to viral advertising, which is all the rage.
