1. Isn't an issue for me as I use multiple browsers on my phone as well. (The default was terrible and I never used it - making it the perfect tool for this).
2. I agree, which is the point I was making above. However we're just awaiting Grujah to flip now, and assuming Smeagol is telling the truth we'll be in lylo tomorrow. While I'm not super opposed to headclaiming, it feels against the spirit of the game - and at this point the game is probably close to over anyway.
3. Isn't an issue for me either, as my other head decided he had more demanding personal obligations, and backed out of this (along with many other games). Finding a replacement seemed silly given the nature of this game and how many were alread "playing" away.
4. See 3.
I recognize of course, that just because they don't hold true for myself, 3 and 4 (and even to an extent 2) could discourage posting here. Ultimately though, like I said, the game theory sounded cool, but I just don't think that it's practical.
