For those of us who do, "ease of modification and fixing" is *very* important. I have *never* seen any piece of significant software that was bug-free. And I've been in this business for 15 years. Listserv has bugs. Listserv has places where it needs to be modified to fit into our local environment. Fortunately, Eric designed it so that I can make the modifications, and Eric can ship fixes that "drop in" easily. So if there's a problem, I can have it *fixed* within 24 hours, and have on occasion (Thanks Eric for dealing with some of the screwy things we've broken Listserv with). As an alternate example, the IBM 'TCP/IP for VM' product is generally admitted by all, including IBM, to have a terribly broken software service scheme. The result is that a site can buy a new 3172 Ethernet controller for their IBM mainframe, and then have to invest several man *MONTHS* in order to straighten out all the pre-requisite patches and fixes in order to install the patch that provides support for the 3172.
