Here's a few more questions that i've thought of.
Should there be three strikes rule?
Housemates allowed to discuss nominations openly?
Head of the household idea?
This has been touted as a possiblity for BB4 and it was tried in the US version.
The housemates vote for this every week and this person gets more privileges.
Another question. Probably doesn't make much sense.
If you could choose one housemate from the three series of Big Brother that represented the type of personality you want to see in BB4, would who it be?
