Although I usually work with RAW files out of personal preference, the jpg files straight out of the camera are perfectly adequate in most cases. The advantage of working with RAW is that much more information is preserved, and as Rod says at the beginning of this thread, this gives the opportunity to 'develop' the image to one's personal taste, or to recover detail which might not show up in the jpg.
On the wider issue of minimising warts on the image, a lot can be done at the taking stage, both from the compositional and technical view points. I don't claim to be a good photographer, but I can quickly spot a duff image (particularly if it is one of my own). As someone who grew up using film, I still like to get it right at the time of taking the picture. Many times I delete images almost immediately from the camera's memory card. Modern cameras have very good auto-exposure and auto-focus systems, but it is still desirable to have the skill to know when to over-ride the auto settings. One of the most useful features on a digital camera is the over exposure alert (usually indicated by flashing highlights). I often adjust the exposure setting after I see flashing highlights, but I suspect many people don't make use of it.
As to the general quality of the images submitted to PoE, this is certainly variable, but technical quality is not everything, and there are some shots which may lack quality but are still interesting in other ways. It is clear that PoE is not primarily a photo expert site, nor should it be, since there are plenty of other forums for these discussions. I am surprised though, along with Rod and James, that there is barely a scintilla of interest in the photo threads, considering how many people submit pictures.
PS to Rod, I hope you don't give up on PoE just yet, I am always impressed by your contributions and amused by your comments.
