Note that Rosco already did take a crack at a few, including generating some
images for them, and in doing so, found a problem in one I created, and caused
me to decide to add fields to the connectionTypeBox, which is goodness. Thanks!

I saw a couple other people adding comments (corrections, expansions, links to
good external articles, etc) to the talk pages associated with the entries,
While that's awesome in its own right, I'd like to encourage people to be
bold... Edit that info right into the main article if you're sure it adds
value. (after peeking at the article to grok how the tagging and layout works)
Wikis can be edited by anyone. (Just please consider setting up an ID first so
we can tell who did it and so that communication back to you can happen)

I agree with all that and certainly would love to see it come to pass.
However, my thinking on the stuff being put in BrickWiki though, is more
"encyclopedic", that is, it's an explanation of what's possible rather than a
constraint system. New builders often ask "how did you do that, how did you get
those things to connect that way" and perhaps these entries would be a resource
on how to do things. More techniques in the toolbox means better builders,
faster. And that means builders who enjoy themselves more, I think.
If LSC actually does get a lot of data, I'd be after getting someone to try to
write a bot to inhale it and create the connection box info.
(there could be a parallel of sorts in setting up information on how to do SNOT,
what sorts of things turn what angles, and information on how to do offsets,
what sorts of parts arrangements give you a 1/10 brick horizontal offset, or a
half plate vertical offset, etc...)
