Noteflight is a great site and support is very responsive, but I've been on it for a year and a half, I've put a lot of time into it - I've even become a Crescendo member - but I still don't have a solid sense of community and, out of 100,000+ members, I feel "connected" to no more than about 8...and that, only tenuously. It's hard to believe that the provision the site makes for personal interaction between members is STILL only via song comments, and in fact, if a member has no songs of his/her own posted, there is NO way that that member can be actively contacted.

I'm afraid that, if it isn't there already, Noteflight is going to end up on the down side of the bell curve sooner than later. The issues regarding the need for a social infrastructure really need to be addressed - I do hope you're well past the "interested" stage and very close to the "we'll be making it available any day now" stage!
