Personally PerlMonks is a place to try code out, get feedback, and then revise it. CPAN is a place to put code that I think will be more useful which I am also willing to support. Where there is overlap, I will post code here first for discussion and also upload to CPAN. If I do that, I want people to install from CPAN. The version that is here will not be maintained. Conversely most of what I post here will never go on CPAN. Why not? Well first of all it is more work for me to get it CPAN ready, secondly it isn't modularized in a way that I think makes it useful on CPAN, and thirdly for one reason or another I am not willing to support it.

Now I am not against the centralization of software archives, for good software. However I also think that random repositories are only as good as the people feeding then. There is no magic that makes a would-be CPAN author any better than Matt Wright. Indeed I think he is more competent than some who have CPAN accounts. But I don't think that there is any value in throwing every piece of good software onto CPAN for public enjoyment. Or even in throwing every useful piece of software up there for public enjoyment.

If you disagree then I suggest putting Matt Wright's Script Archives on CPAN, in their entirety. After all that is code with a demonstrated utility to the general public.

As for what Elaine Ashton has to say, links please. After I read it, I will give an opinion on what I think.
