I kinda would rather they didn't, but I was also kinda against the Michael Jackson tribute item as well.
There are lots of people who've died over the years, some famous, others less so. It's kinda unfair to pick and choose who was important enough to warrant such items, and who isn't.
There wasn't a tribute when Gerry Rafferty died, or Harry Morgan, or Corey Haim, or Jeff Conaway, or Andrew Koenig. Too obscure? How about Andy Rooney, Bill Keane, Peter Falk, Peter Graves? Still too obscure? Elizabeth Taylor, Randy Savage, Leslie Neilson, Tony Curtis, Gary Coleman, Dennis Hopper... and these are just people I like, there's a lot more that I'm sure others cared very much for.
So, how do you decide who's worthy? I honestly think they just shouldn't, but that's my opinion.
