My question about why some posters will not even consider a paid model (whatever form it takes) remains. After all, we have all spent tens of thousands on gear over the years (some way more than that!). A modest amount per annum to cover the essential aspect of learning how to use one's gear better, and to learn the myriad aspects that go to making a better image, seems reasonable to me.
I think Olaf's model of donation is the best way forward and I laud his reasons for doing so.
...and no, we all haven't spent tens of thousands on gear. We're not all 'well off'.
Not everyone who visits this forum has the financial clout that some do. Due to the current economic situation, exacerbated by the actions to stem the spread of Co-19, some photographers, professional and amateur alike, are suffering financially. I know a photographer who has no more than £100 in the bank so she is very unlikely to consider a subscription to anything. I myself am stuck in a country I can't afford to get out of at the moment. Thankfully, I have a lens I can sell to get out (I hope, eventually).
Admittedly, photographers in such dire financial straits are not going to be visiting forums much as they have more important things to consider and will neither have the time or opportunity, but they should not be inadvertently excluded on the principle that they have no money.
If those that visit this site regularly, get a lot out of it, and are financially very secure then they are free to donate.
In case someone is thinking 'freeloader' in regard to those that don't donate, I should also add that those who are not financially well off (think mostly pro's in this regard) may also be amongst those that are able to provide information that many amateurs and maybe a few pro's seek. I myself am a pro' (a very poor pro) so I'm more likely to provide information. My speciality is macro and wildlife (30 years worth) and I know what I'm doing (I think) and I'm really good at it (so I've been told). I must admit I haven't seen many questions on those subjects here, but if I saw them I would assist the best I can. If this site became a paid site then I would not be able to do so.
I also have a very personal opinion. I believe access to knowledge and understanding should be free in the great scheme of things. I have no problem supplying my knowledge and understanding to others for free, and it ranges from how to do algebra to stripping down a car engine to explaining the best way to photograph a tiger beetle. However, I'd be damned annoyed if someone told me I had to pay to provide that knowledge.
1. Many photographers are poor.
2. None want to pay to provide their knowledge.
All the best,
