You know already I disagree strongly with this, at least as an approach for myself. I wouldn't take the risk of memory loss, at least not for film from anything remotely important. If I wanted to wait months before editing, if I truly believed that would help me become more objective, there's no real reason I can't immediately develop & scan it, have a general idea of what it all looks like, give the files names that help me remember the details...and THEN not edit them further, not print them, not show them to my friends, not post them publicly anywhere for months. To me, the lag on developing has nothing to do with giving yourself time to edit.
I think I edit myself quite strictly as it is. Thus far I don't think I've ever looked back at an old photo I once thought was great and realized it really isn't...or if I have, it's an extraordinarily small ratio. Which is not to say every photo I print/post is AMAZING... but even with the just-ok photos, I had good reasons for liking them, and after years go by I'll relook and still find the same reasons.
On the other hand, I have with time found photos that I thought were only so-so to be pretty damn good, so I definitely enjoy looking through my archives for those...
