Well, I just answered the original question in the title - "Does anyone use Perl on Windows?"

Context clues. You're purposefully ignoring the entire point of the post:

I need to know whether my work on berrybrew is worthwhile or not.

Are future efforts worthwhile?

They're not just looking for people who use Windows; they're looking for people who might potentially be impacted if berrybrew is no longer maintained. They want to know if anyone is making use of something they spend their time working on. You aren't in that group and it's not because you've found an alternative solution or feel like berrybrew is complete enough to be put on the backburner. You're not in that group because you're fully against the philosophical and practical aims of both berrybrew and Strawberry Perl. It feels like you jumped into this thread just to dump on both projects existing at all and that's what bothers me the most. Someone starts with 'does anyone care if-' and, without missing a beat, you leap out of your seat shouting "I don't!" That's how I read your comment and, looking at the votes, it's how several others read it as well.

Every other person here is talking about co-maintenance, keeping the project alive, and sharing their experiences but not you... The rest of us understand that we all need projects like Strawberry Perl and berrybrew to thrive even if we don't use Windows, Strawberry Perl, or berrybrew personally. But you don't even care that perl itself is still maintained. You've decided you're not even interested in the last 20 years of performance and security work done to keep Perl alive. You aren't even interested in the work put into the standard release of perl 5.8.x. Finally, you don't test projects on a range of versions and you aren't maintaining software for CPAN or a Darkpan wider than your desk. I hate myself for saying this but I'm not even sure if your 2¢ even amounted to a useful datapoint for OP.

He wasn't talking to you.

I won't argue with you because I'm convinced even holding a cordial conversation with you is a massive, frustrating waste of time but he wasn't talking to you.
