Pros
Angie's List has a great company culture as I was lucky enough to work with superiors who were truly invested in my success and well-being. The hoky department in charge of corporate culture/happiness wasn't needed, because the people made it exist and the from the CEO all the way down the message was that we are a family that takes care of its own. Of course, you have disgruntled employees--sales is hard and not for everyone, but those who had a talent for it and worked hard found success almost invariably. Those that tried to coast, hide, or do just enough often found themselves frustrated.
Cons
The biggest drawback was that the IT team wasn't up to the challenge of taking the company where it needed to go and hence they found themselves bought by Home Advisor after falling way behind. It's tantalizing to think of where the company would be right now if they had top-notch IT development abilities five years ago. Perhaps the merger will help in this regard.
