Everyone cares more about the Defiant than about Jadzia Dax. When we get Ezri Dax we get a different character with a different personality. When we got the new Defiant it was just the same as it would have been with the old one. Jadzia and Ezri are characters, the Defiant is a ship... oh, no, I`m turning into McCoy, consarn it!
Was this site up when Jadzia died? If it wasn't, then no one talked would have talked about it because there was no site. If it had been up when they killed her off, I'm sure they would have talked about it a lot since it would've been fresh in their minds.
