The problem with the results being visible and the whole "teaming" thing is that it is completely illogical. It's not representative in any way and it's not like people actually team to save a song that's seriously in trouble, it's basically half-random and screws up the entire results. An example: we've got a survivor with four songs, let's call them Day After Day, Turn The Key, Let It Out and Freedom (yeah, I know). After 6 hours, the results are...
Day After Day - 1 vote
Turn The Key - 6 votes
Let It Out - 3 votes
Freedom - 0 votes
Six people who love Turn The Key enter the thread. PANIC!!!!!!!!!!!!!11 They'd vote for Freedom as it's their least favourite, but it won't save Turn The Key. So, let's vote for Let It Out as it has three votes already. And we get...
Day After Day - 1 vote
Turn The Key - 6 votes
Let It Out - 9 votes
Freedom - 0 votes
...and then, it turns out there are 5 more people who would love Freedom out this round and enter the thread later. Six people had wanted it out as well, but they decided to "vote strategically" to save their favourite, so there's no real chance to eliminate Freedom now. Even though it normally would be.
This is an example made up by me on the spot, but it actually happened more than once in 2009. It all goes down to which song gets several votes first, not the one which is really disliked by the most people. This completely messes up with the results, and you get such ridiculous situations like the whole "Operation: Scarred", which basically made every single round a duel until it was gone. This isn't exactly the point.
