Hey thanks Stuart. I agree with everything you say here. I think it's just more familiarity so that all the little nuances of the playing and the phrasing of the singing blend together. I actually think the timing of uploads is quite critical. I think one needs to work on the tune for long enough to get it to a point where people can make some useful inputs (as I have received in abundance here), but not so long that all that is left to say is "great job". I mean, it's wonderful when people post a brilliant video and we have several members who do that regularly, but the videos for review are a great tool for everyone so it's nice to have some technical comments. I think the busking and review live very well together as they each serve a purpose. Massive kudos to Chris for solving that problem for us!
That was pretty long-winded! Thanks for commenting Stuart.
