I wish to direct your attention to a blog post made by my friend and fellow System Center MVP Tao Yang. He is talking about community efforts and contributions and on how some of them get turned into commercial products. If you are working with SCOM for instance you will find many management packs and scripts and solutions and thoughts right from the community. You will also find some great paid solutions written by serious software vendors who add value. There are also cases where both options are available and this is a point where you have to think on how to spend your time and money wisely. (By the way a great way is supporting a dog charity, look to the right of this post!). Power to the community. Please read his blog post:
