OK, so I guess this is what I do now here, complain about things people are sharing on Facebook too much. My Facebook friend Phil shared this just now, and while I agree with the sentiment in theory, only because so many bands bitch about how "no one supports the scene, maaan," then peace the fuck out as soon as their set is over, often times unloading right in the grills of the next band up, I'm not sure I can endorse this particular strain of whinging wholeheartedly.
Here's an idea to consider: if you've got such a shitty draw that the audience gets noticeably smaller when the 4-8 other dudes in the other bands leave the room, then maybe you should rethink that whole 'being in a band' thing, because it seems like no one wants to see you.
