Very interesting idea, Matt, about a creative site rather than a gear-centric site - there are quite a few of the latter but I haven't found one of the former that I've ever bookmarked. A possible idea I have concerns two distinct areas of creative origination: That which inspires
Such as suggested films that have appeared on this thread. Perhaps a list of films could be created with various peoples explanations added about why (from the point of view of story construction, cinematography, characterisation, dramatic situations, etc) people find them inspiring. Could also include painting, music, TV, still photography (other media that inspires), though that might be straying too far. Initial exploitation of ideas
There are quite a few "how to write screenplays" sites, with advice about 3 or 9 Act structure, plot points, how many pages a treatment should be, etc, but I think one of the under-reported issues are how you handle the initial ideas before writing really starts. For example, formulating a powerful "what if statement" (to help you focus the key concept which will hook interest). What makes a story alluring; what sort of themes or subjects appeal to you? Discussions about style, ways of seeing and personal ways of showing.
