Time for a proportion Z-test! Assuming that this poll represents 
a simple random sample (which it almost certainly doesn't, but 
it's the best we have), let's test the claim that at least 50% of 
the community dislikes the SDL format.

For reference, I'm using the poll data at the time of this post: 
124 for, 145 against.

According to my calculations, at a 95% confidence level, there's 
not sufficient evidence to reject the hypothesis that at least 
50% of the community dislikes the new format.

However, FWIW, we can say with very high confidence that at least 
25% of the whole community likes the new format.
