whatever happens, I hope they dont run it for too long with only a handful of housemates. the last couple of weeks are always dull due to not being enough people left in the house..... if that were to drag on for a month
as for the public voting who goes into the house... oh great... a house full of camerons and nadias?!
The only way I can see for a long bb to work would be if every week there was a normal eviction, with phone lines closing for that on the friday. From then until saturday night the phone lines are open again, but this time you vote to either put someone new in (a choice of two people each week maybe?) or an already evicted housemate. After that the phone lines then go back to voting for next weeks eviction again.
This would mean that you'd get most of the way through the show with the house still being full of a good range of personalities. Plus people evicted by mistake can have a 2nd chance (like mr tickle was given a 2nd chance and anoushka should have been).
When the show gets two weeks to go, the phone lines are then purely open to voting for the winner... and on each day of the last week the person with the least votes goes. An eviction every night for the last week would keep it really interesting right up until the end.
the details need a bit of work, but I reckon generally that would work out really well without the teenie girl and bored housewife voters having chance to ruin the it.
