Many open source amiga apps have become successful, been ported across multiple amiga platforms, and still get a little tlc even if not actively developed. however if you take the attitude there is no point, and don't do it, then of course, nothing will improve.
it's your project and your choice. but I think you are wrong regarding this. I actively work on multiple open source projects. it was the fact i could pick up and hack the code that got me started on them.
And many do not become successful, are completely abandoned, or relegated to commercial development.
There is an Apache module I need for my web server. While I have programming in my background, I do not have the time to tinker with the inner workings of Apache to learn how this module works or to recreate it. The author is uninterested in updating his patch, and only a handful of Linux distros have maintained this module. And those distros are useless to my Solaris installations.
There are a number of really good FOSS projects which simply become abandoned. In theory, the nice thing about FOSS is that the motivation for a project is not money, but rather the usability and necessity. Until the developer or developers no longer find it necessary for themselves. So, in some ways, I feel the flaw with FOSS is that projects are often necessarily selfish.
In any case, I, too, am very interested in a 68k Roadshow, and stand ready.
