This is why we have all sort of software. For some its "reinvention of the wheel" for other using and liking the software is "the wheel as it should be". One advice I would give to anyone is never lose motivation about your idea. There are no good or bad ideas, only ideas that are not mature enough. Don't let people that are very loud expressing their dislike , make you lose motivation on your project. Everything with work can improve and will improve. Its the effort you put in.�
Most big inventors were considered "crazy" and "outcast" anyway. It takes time to really appreciate things and for them to get to a level that show their true potential. I am definitely very excited to see all these Pharo projects pop up like mushrooms. Nothing better than highly motivated people :)�
