That one death page on TVTropes does explicitly mention near the top that there are spoilers. But you know on every other TVTropes page you're going to highlight the spoilers anyway.
I do like the idea that some tropes (okay, many of them) are named after characters or shows, so you automatically have some idea what they're referring to just by title. You probably have an idea what a Ralph Wiggum character would be. And if not, the trope name's highlighted so you can just click it to find out. Usually there's a picture to go along with it that explains the idea faster than the text does. And if you still have no clue what it is... just read a few of the examples. But then it's 5 hours later and you've forgotten what you were originally looking at.
Ditto for lampshading, never heard of it before. I still think it'd be better to define it more bluntly as "explicitly pointing out the trope." I don't really know what is meant by hanging a lampshade. I'd think of covering a lightbulb with that little frilly lamp cover. I wouldn't think of pointing a lamp or flashlight at something.
One of my favorite trope pages is
Conspicuously Light Patch, which is the tendency in cartoons to have a part of the background that's going to be used stand out like a sore thumb from the rest of the background. That and
Made of Explodium.
...and I think it's really silly that my browser would mark a URL as being a spelling error.
