I've almost replied to this thread several times and I'm glad I haven't before because now I can say "what Linda said".
For me the challenge is taking a picture every day, not posting one every day (which I often don't). My PaD isn't called my Daily Discipline for nothing - I need to have the discipline of having to take a picture every day rather than when I have time for it, to keep me going. I know I've put up pictures which aren't up to the standards of better photographers but I also know I've improved a LOT over the last year and half or more and that the improvement isn't just down to better equipment (though it helps

). There are still grab shots but there are also pictures I'm really pleased with. Ones I took at the end of a really hard day, when I was knackered and didn't actually want to do it but then got into the zone when I got going. So, it's a curate's egg, good in parts.
Declaring my interests, I've never met Linda or David, but Linda's PaD is the reason I PaD.
Of all that I've said above probably the crucial thing is the phrase "for me". That's what works for me, it doesn't have to work for anyone else. We all have to find what works for us. And the main thing is to ENJOY what you do, whatever you do. As Linda said, it's the challenge "within" that matters and I don't think anyone with rules different to mine is a cheat, just as I'd hope they would't think I was a cheat because I don't post every day. I've found the PaD'ding community to be warm, welcoming and supportive.
As for the abuse of the meta gallery (which I think came along a little later than Jan 2004, Ray, possibly not until spring that year because it definitely didn't exist when I started PaD'ding) - if there was a similar gallery for recently uploaded pictures to *any* gallery, that showed rather than just the "recently updated galleries" list, I think we'd have far fewer obvious abuses of the PaD gallery. I don't know how feasible that would be but I think it would help.
