I think we need to go back to the motivation of Alan's post.
It is not that members in general don't want critique (maybe the odd one doesn't - but that isn't what this is about).
Many of our posted pics have the odd flaw. The intent, story - call it what you will - of the pic carries it and the flaw doesn't matter. Maybe the poster couldn't be bothered editing it or maybe he just doesn't care. Most of the time the flaw is nothing major. Even if it is, it doesn't matter - the intent of the post is the story in the pic.
Occasionally someone will comment on one of the posts and point it out or make a suggestion. It is never an issue for most posters on this site. Even if it is, we all just move on - no arguments, no ill feeling. The occasional comment is part of the general conversation of what we could call a healthy forum environment.
So what was the motivation for Alan's suggestion?
When someone continually passes critique in general forums people get frustrated. Especially when the critique is either obvious, or misses the point of the post. It kills positivity, leads to frustration, which leads to arguments and the site suffers. The environment becomes unhealthy.
Alan's suggestion is making an effort to put out all the fires caused by excessive critique in the general forums. His motivation is for the benefit of the site.
Unfortunately if it is taken literally the site also suffers. As stated, a small amount of critique is to be expected and benefits the site - stopping that is a step backwards. Unfortunately it also leaves the door open for comments like "it's a nanny site", "people can't handle honest criticism". Comments that are true of some sites that don't favour any critique. I don't think this site can be accused of that and will never go down that path.
What's the answer? Some form of restraint? "You have reached your critique limit for the month / week / day - any further critique will lead to action" Sounds childish. But that seems to be what we are dealing with.
I know the enforced holidays leave many of us in a relaxed mood for their duration. Maybe it would work...
