I have too many other GD pages that I contribute to.
I'm shy and don't like to post things on group pages.
I don't know enough about the GD to post or comment.
Most of the posts are boring.
This page sucks and I forgot to unlink myself.
This page is so amazing that I'm too intimidated to add my own measly content.
No particular reason; I just like to read and listen and leave it at that.
