Not the way I cook my burgers - I like them thick and juicy, almost purple in the middle (none of that 90-95% lean crap) - cooked rare, even with cheese and ketchup (the proper way to eat a cheeseburger), the flavor of that meat is easy to taste - and damn it's good! Been eating rare or medium rare burgers my entire life and have never gotten sick from one - biggest problem is that many places will not serve a medium rare burger, only medium, and nothing is grosser than tasting the burnt meat on the outside - plus it's carcinogenic. How anyone can eat well done meat of any kind is beyond me - it's dry, burned, and tastes nasty. Steak tartare is amazing if you can stomach eating raw beef, and I have no problem with that, although I could count on one hand how many times I've ever eaten it - just tastes better when the juices get flowing from heat.
