Fluxx is filled with very dynamic, interesting people who were a joy to work with. The underlying technology was also very robust and fun to learn more about, and the location is great for exploring SF.
What I wish was different
Some people worked with the company remotely, which made certain tasks more difficult than they needed to be communications-wise. I also wish I had more chances to present my work to management/executive teams.
Advice
