I think many of us feel what the most active ones here have already described, that the result is "doomed" to be chaotic, but the cause is so good and the effort so high that you just got to love it! I guess we'll see the full effect after the release, but so far, which artists have posted something? I don't follow a lot of guitarists. Clapton has nothing, same with Springsteen. Facebook suggested a Springsteen fanpage where it was mentioned. One of the replies was "I didn't know he (Mark) had a solo career".
