Well, you didn't ask if appreciation was good, or if it was uplifting. Of course it is. Who doesn't like to be appreciated?
You ask if it was important. And I stick by my answer.
I mean, yeah, it's gratifying to get a hearty round of applause for a chorus or two from strangers somewhere. That always feels good. But is it important? Do you define your worth or lack thereof by it? Can't say that I see much good in being at the mercy of strangers all the time...
Otoh, appreciation or lack thereof for those same choruses from somebody who you know is on the same page as you, well, that's the type of thing that either confirms your instincts or causes you to reevaluate.
Of course, I guess it depends on who's on your page. There's the White Pages, and then there's your private phone book, if you know what I mean. They each serve a useful purpose, but I'm not sure if having too much of an overlap between the two is the way to go.
Again, just my opinion.
