I would also like to see wall posts be a lot like answers.
Voting (up/down) is not required, and might be bad. Voting up/down could be done with or without points. Points could be Q&A points, Meta points, or a new type, wall, or 'internal reputation' points.
My reasoning for this is that we have a single item which gets marked private or public, which contains the entire context, and is more difficult to remove the context and make one comment out the middle of a dozen public.
This idea is less important then the pub/pri mark, but I think it moves the idea along to a more advanced (2.0?) design.
Oh boy, then somebody gets to add '''''this''''' to the FAQ...
