No doubt AWE converts and retains - they have a great combination of very good performers - in every sense - and relatively cheap private chat rates.
Add to that 2-way video, full-screen option, audio (some performers) and even a VIP program with rewards (free chat credit), it's little surprise they are doing so well.
For webmasters they also have a draw at the end of each pay period where you can win up to a $2500 bonus!
