Awesomium is good but development is excruciatingly slow and the team seems to place no importance whatsoever on developer relations. Questions on their forum are very frequently ignored, and I've heard that the situation with email replies is similar. If you have an issue that maybe they haven't dealt with yet, they just ignore you, because perhaps it's easier to cover your ears and eyes then to address a problem that folks are having.

Awesomium team, if you're reading; guys! Get your customer relations sorted out! Answer every damn forum post! Make people love you! Many developers are using the free version of your product, but these are the same developers who will recommend that their employer buy your product. Your failures in these departments have stopped me from coming back or recommending your product to others. I can't speak for others, but I wouldn't be surprised if others feels the same way.

Disclaimer: I say all this with no knowledge of how overworked or understaffed you are, what technical problems you're currently facing, how much time you would need to spend answering questions or why the time between updates to your product is so huge.
