Any smart person, pro or amateur is going to look at what an application can do for them - not what someone else is doing with it. You use what get's the job done. I suspect other factors, stability, 3rd part support, ease of integration with other applications have more to do with it than anything else - for the smart person. There are always some who allow the irrevelant to sway them.
