Well, it's something you sadly have to face standing in the spotlight.
That's why I admire everybody, who's standing on stage singing, as you open up your heart and soul for the audience.
Critique should be welcomed, but it always depends on how it is phrased.
Sometimes it just helps to rant about it to let everything out.
And I know how you feel with unrecognized fan love. There are quite a few artists I love to follow, who doesn't have a thread here, not to mention even be known here.
That's why I like JPop Central, as it is at least a bit wider in music taste for lesser known artists. Though you also don't find everybody there.
Sometimes it's just unfortunate to be a foreign fan.
