There are a couple comments here saying that software developers shouldn't bend to the will of a vocal minority that doesn't like change. I completely agree.
However, this is not the case here. I use Skype daily for business and I can say that not a single person that I know who upgraded likes the changes. That isn't a few squeaky wheels.
Granted 20 people isn's statisticly significant, but when it is hated by 20 people in a sample size of 20 you have to wonder a bit.
I'm sure a lot of people love it; but I'm not one.
