Superheroes and the like

I recently read a friend's blog, who mentionned Superman. So, I've been wondering something about that dude. Since everything in that guy is "super duper", everything we can see, at least, why oh why does he wear his underwear atop his trousers? Although it's thighs, more like.
Not that I expect any kind of answer, mind. Just needed to get it out of mine system.
Now that it's done, well... I kinda find myself at a loss, really. I know it's old news now, but I can't seem to get over Marvel killing Captain America. Admittedly, he was way too old for his own good, but why not let him fade into the night, instead of killing him? I mean, it's not like Marvel ever respected the passage of time... The son of Reed and Jane Richards managed to stay three years old for about 5 of our years, and then all of a sudden grew up to being roughly 18. Not to mention Spidey's various tribulations, time-wise.
That's why I don't read comics anymore. That and cross-overs. Whoever invented that was a devious genius, and should probably be the target of a swathe of anger from readers all around the world. Although the sales exec probably rever him and sacrifice young readers to his glory, in some lost, dark publication company's basement.
Fortunately, the good folks at Vertigo have enough good taste to produce satisfying products. I'm a huge fan of 100 Bullets, and of course titles like Preacher are always good to read.
Anyhow, enough geeking out for tonight.
Cheerio!
