... are people too nice to say anything or do they really not notice?
My own view is that people ought to say when a shot is out of focus.
My personal view, given that this is a site used by a very varied group bound by a shared interest, is that there is nothing wrong in saying that a photo is out of focus when in the wider context of a post that, at the very least, makes a nod to the concept of constructive criticism or a desire to (genuinely) help.
As one who has no desire to 'go pro' or may well not have any motivation to produce the kind of shot you look at every day, I am happy to view photos others post and take into account the subject matter, composition and general 'feel' in order to gain an overall impression.
Does the fact that they are 'soft' or OOF detract somewhat from what they 'could' be in a perfect world? Yes, sometimes it does and (especially talking about my own poor attempts) it can be an issue.
However, firstly, I think that it is a shame that your professional role has brought you to the conclusion that no-one should bother to do anything or be proud of what they achieve if they are not able to be a 'master' of it.
Secondly, I think that maybe you have focused (
![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
) too much on one aspect of what is, to many here, an enjoyable hobby - a way to share what we do and to learn from each other (even when that includes being told our photos are out of focus).
Finally, I am not, as I said, in the business of photography. I enjoy what I do. I try to evolve and learn. I even try to focus occasionally. I do not, however, intend to spend the rest of the time I practice my hobby worrying about whether some guy on a forum considers my 'work' of so little worth that I should delete everything I have posted here or on Flickr or wherever else I chose to place it
P.S. Having seen some of your other posts, you seem to be a little grumpy in general. Maybe you should see this forum for what it is and go to one of the professional sites of you 'really' want to offer the kind of critique you seem to think we should all be crying out for.
