Note, this is about layout as in "desktop publishing", not VLSI circuits.

It’s interesting to me how often papers do this, where even after reading the abstract, it’s hard to tell in what context they’re using key words, and by extension, what the paper is actually about.
My loosely held feeling is that this is also a pretty strong indicator of what you’re going to be in for in trying to digest the rest of the paper.
