Nice start. Some comments follow:
I like the pre-review steps. I haven't always done the check to see if it is an existing article, but it is easy to do, and would save a lot of discussion if it does exist, so I'll try to incorporate that into my routine. Similarly, I haven't regularly checked for copyright. Sometimes, if the wording seems too professional, I have checked, and found occasional problems, but I probably need to make it part of a routine.
I'll use this discussion to mention a personal rule I tend to follow: if someone goes to the effort of asking for feedback, I don't feel right sending it to Afd or prodding. I doubt that I have policy backing for this position, but it just doesn't feel right. (Obviously, in the case of copyvio or a BLP attack page, steps must be taken, but when it simply doesn't pass muster as is, I'd prefer to point out shortcomings, and not try to wipe it out.) I don't even propose that it should be a rule, more of an informal agreement, unless someone persuades me I'm being a total wimp, and we are better off being tough.
Regarding the purpose section: another personal rule I've adopted is that RFF is for review of articles at an early stage, but not the place for quality assessments. It is my observation that quality assessments tend to be done by Projects, but I haven't seen that written anywhere. If it is written, we could link to that advice, if it isn't written and we agree, we could write up some words to that effect.
Should we encourage adding a talkback after adding some feedback> I do it and some others do, but if it is considered a good practice, it belongs in the guidelines.
In the case of a user subpage, I think it makes sense to place the feedback at RFF and a talkback to the requester, but in the case it is an article in main space, someone suggested adding the comments to the article talk page, so that over-eager NPP might seem them. I thought that sounded like good practice, but let's discuss.--SPhilbrickT 16:40, 2 October 2010 (UTC)
