-Change the way POV (in fastings) and HoH (in frookies) are chosen. I am not very fond of the 'plussing' way of getting power/safety. Its a little too abstract for my own liking and I don't like non-quantitative things. Maybe a better approach would be who is more active (in regards to plussing/negging comments, sending messages, posting, and voting.)
-Have an automatic eviction for anyone who goes over 15 minutes with an option to take a Leave of Absence (for a given period of time) for anyone who has to take a break for something. This could be for fastings/frookies and would make the game alot less of a hassle for the rest of us active players!
-Have a way of group communication actually on tengaged. I am very tired of having to risk chatzy and such. It would be super cool if there was a way to communicate through the website as a group for an alliance. (I also think there should also be some way to expose it.)
-Make competitions more meaningful in regular castings. I feel like keys and plusses are far too powerful... again, its my quantitative need! ;P
-Have more twists in all the game. For example, bring in some of the twists that big brother used in past years and make some of your own! That would make it much less of the same game and more unique each time you play it.
I don't know, I just feel like there are so many other cool ideas that we should tap into. Share your ideas! :)
