Hi Philippe,
Thank you very much for your nice words. I don't know if PixInsight is as good as you say, but you can be sure I do all I can do to make it better. This is my personal project and I am betting everything on it.
What you are describing is a consequence of resistance to changes. This is one of the main obstacles to innovation and development, and exists in the astrophotographical community just as in the rest of our societies. There's nothing original or new in this fact; it is a well-known sign of our times.
One of the important things I've learned during some years in this "business", is that patience is essential to develop a project like PixInsight. I could tell you many histories of disparage and lack of respect, especially in some instances and by some people that one would never expect to behave that way. Of course, I won't tell them, mainly because I always prefer to look ahead.
In its current stage, PixInsight is much more than I ever could have imagined. I enjoy as a child working on it (although it is extremely hard sometimes), and this is just the beginning. Not even that; I feel we haven't yet started
I have a lot of exciting plans for the future; dozens of new tools and improvements, including some really advanced developments.
So I am optimistic. We have 251 commercial PixInsight users as of today (the list above includes the users that receive new version notifications, which includes trial licenses for the last four months). Not many, but not a bad number at all, considering that we published the first commercial version in January 2008, and that we have very limited resources. And much more important than that is the fact that all PixInsight users are really nice people. I am a lucky guy for having all of you in this project.
