Saw one very good demo that one of our customers will love, and they are going to send me an email when it has been loaded up onto codeplex, so we can get it, customise it, and demo it. So certainly not wasted time.
Also made me focus, being surrounded by a bunch of creative, goal-oriented professionals. Always more to learn. Made me realise that I need to use these winter nights and weekends productively to acquire skills and certifications.
