My folks just spent 4 weeks in the US and I was tempted to ask them to catch one over there for me (ie log into my account and catch it) but decided against it for fear of being banned. Would have been nice though.
On the popularity side, yeah the game has died quickly. This is what happens when they open the game only partly finished and don't provide any major updates since it came out. I had a FB group that was active daily, now it is down to maybe 1 or 2 posts from members a week.
They are so focused on rolling it out to other countries that they are not providing current players with incentives to keep playing. Only so much appeal you can get from constantly throwing pokeballs and gym battles.
I turn it on maybe once a week if I have nothing better to do. Otherwise I'm done with the game until some decent content arrives. It shouldn't take this long for PVP, trading and a better system for raising and battling pokemon.
Don't even get me started on the battle system which is just a tapping frenzy, no skill really involved. I miss the old Gameboy battle system.
