Has to do more with end user. People want the mystery: are they alive, are they dead, did they implode, are they floating on the surface some where. If they are alive there's a million questions about it. It's just the way of the beast.

I also think it has to do with proximity - this happened close to "home".

People are also stupid, some of the questions they were asking and stating that it's a conspiracy because if the titanic is still whole how did a sub implode because they arent sure how a pressurized chamber works is astounding.

To follow that, they probably don't know where Greece is.

Exactly.

That kinda makes sense though, since there was no ongoing rescue/recovery operation to talk about. There's only so many articles you can write about a bunch of people drowning.
