I don't have an opinion either way when it comes to what to do with a thread but I do think posting about every dead celebrity, even ones who's concerts you've never been too, who's records you never bought, etc is lame in the first degree.. If you don't care about them (hint: you probably don't) then to do something else.
I had network news shoved onto me for a few minutes today and I was just great to see scumbag hacks using possibly their last chance to mention the drug problems and whatnot of certainly recently deceased FPs they've been mercilously hounding for decades. That's clearly the negative side of rubber necking, but they aren't the only ones. Some are compelled to head to Wikipedia and study up on a celebrity they haven't pay attention to in 15 years if ever and then run to make some facile thread about them on EVERY SINGLE WEB FORUM as well as Facebook and Twitter.
Recently Slate decided to do a week about Stevie Wonder precisely because he wasn't dead yet. I think it was a good idea. Got me listening to Music of My Mind with my kid and that's a good thing. Also, his XMas record, of course.
