Good lists and I agree with your Pick assessment. I would like to add that it is the "agility" (unfortunately now a buzzword) of a post-implementation system written in PICK that has made it so viable for so many vertical industries. The number of software applications developed and maintained over the last 20 years is truly amazing. I will grant that often the "refactoring" has been whatever the site can get away with, rather than what would be the best solution, so 20 year old software has a lot of awful "stuff" in it, but it has been handily (inexpensively) maintained over those decades none-the-less. --dawn Received on Tue Apr 20 2004 - 08:28:30 CDT
