...Imagine you're at your local indoor wall/ outdoor bloc. You're stuck on a problem. You're mate(s) are also stuck on the same problem. Nobody can work out a slice of/any of the beta.
So, you take a picture of the entire climb and/or some smaller photos of individual sections or holds that are causing you trouble. You then post the photo onto a website (for talking sake we'll say it's called 'givemebeta.com' or 'master[of]beta.com') and number the holds, along with a key linked to a small description (e.g. 'Hold 5: ~10mm even undercling with the possibility of 4mm or so crimp along the top') and some selection boxes, maybe along the lines of the gradient of the wall or 'definitely can't be used as a handhold' or things like that.
The website is setup more or less like a forum (fuck, I suppose it could be done on here in a simpler format now I think about it) so give the descriptions and pics, other climbers can have a stab at some possible beta or obvious solutions that might not have been quite so obvious when you're thumping away at it on the actual wall. Climbers are given credit for attempts at providing online beta and extra credit if their beta turns out to work for the individual that posted it.
Of merit? Pointless? Already done? Honest thoughts?
