Folks: As one involved in developing various scalable tools for informatics computing, I am trying to understand a trend that I think I see emerging. This is specifically with regards to what tools people will use in their own products (internal tools to support research). I am not trying to do market research here, just to get a reality check. There are high quality tools rapidly emerging onto the informatics scene which are open source and hence free (in the libre sense, and in the monetary sense). What I am trying to understand is, for end users or consumers of these products, what is really important about the product... being free in the libre sense (the source code is available), or being free in the monetary sense. I understand the need/desire to have a level of control over the source so that your work will not suffer if the company goes poof (imagine if someone built a business process or research process around DoubleTwist and their tools for example). In this market, in this economy, such inclinations are wise. So I am asking this question in hope of some sort of discussion of the pros and cons of the open source software in informatics may emerge. Some people are virulently one way or the other. I always prefer to have source if available myself. This allows me to fix bugs. The problem as I see it is from a corporate viewpoint, I cannot point to a single successful open source focussed software house in any market (note: RedHat is a services company that happens to have the standard linux distribution). I know the folks at Electric Genetics are making a run at it, and I wish them success. But history seems to indicate that this model doesnt work. Or it could be that different models dont work, and Electric Genetics have a sensible model. I dont know. I would like to hear people's opinions of this. Joe
