While I'm not sure naming and shaming is such a great idea, I do understand peoples' frustrations and I will hold my hands up and say I've used the meta on and off but not according to the purist way it was designed for.
I did do PaD consistently for less than a year and I've toyed with doing it again, for the discipline, as much as anything. Even at that time, I was not working to the purist model; of always posting a picture I took that day as near as possible, though where I could, I would.
This is an entirely personal thing, and I know that many get great benefit from following the purist route, but my vanity, to be honest, prevents me from posting what is in my eyes only an OK or mediocre picture, particuarly to a defined, common audience becuase I find myself asking "why would anyone want to see this crap picture of mine?".
I would sooner post what I regard as one good (or good enough, anyway) picture a day for as long as I can sustain it, than dilute the quality, and that will inevitably mean posting pictures from different periods because I'm nowhere near good or inspired or free enough to take a good photo everyday.
I think if we're honest, people here often express disappointment with the meta because it's fair to say most of the photos on the meta are just not engaging photos. If the majority of metusers are really posting a picture a day from that day, that the majority of photos in any 24 hour perior are not good is not at all surprising, given how hard it is to take even one good photo a week. Of course, there's no accounting for taste, and there are other reasons why you might do a purist PaD besides simply impressing people with photos. Indeed, some people have a PaD gallery and never post to the meta. I suppose if people annoyed with my fair-weather Pad-ing suggest I go and do that, I can't blame them.
However, another thing that bothered me about PaD is that, as a result of my being selective about what I posted, I found that I was putting all my best pictures in PaD becuase I knew it got a greater audience, as a result of which other galleries were a bit starved of what I thought was quality material. Since abandoning PaD as one gallery, other galleries of mine, I feel, have flourished as the lurve is spread around more.
Still, I like the idea of trying to post one decent picture a day, and in the past few months I've been trying to do just that, and where I feel a photo is just that bit better, I link it the meta.
Am I doing a PaD?: Sorta.
Is it still all in one gallery?: No
Do I try not to fill the meta with below-par stuff (which I take plenty of!): Yes
Is my position entirely defensible?: Hell no, but I hope I've shown that people don't play by the rules sometimes because the rules are too rigid, even if they are being a bit naughty and frustrating other people who want everyone to play by the same rules.
It is also true that they are a minority of people who, to use that great British expression, 'take the piss' by linking everything as often as they can in a cynical hit-hunt.
I suppose a solution might be a two-tier system, one meta for the purists with code written to ensure people could only post once every 24 hours etc. and another for 'the rest of us', but I admit both tiers would still run into trouble; not just of the technical variety but because of that most intractable of problems: human nature.
My final thought is that is slightly amusing to see people getting so worked up about it. It really just doesn't matter that much! I know there will be those who disagree...
