Sangamon Taylor's a New Age Sam Spade who sports a wet suit instead of a trench coat and prefers Jolt from the can to Scotch on the rocks. He knows about chemical sludge the way he knows about evil -- all too intimately. And the toxic trail he follows leads to some high and foul places. Before long Taylor's house is bombed, his every move followed, he's adopted by reservation Indians, moves onto the FBI's most wanted list, makes up with his girlfriend, and plays a starring role in the near-assassination of a presidential candidate. Closing the case with the aid of his burnout roomate, his tofu-eating comrades, three major networks, and a range of unconventional weaponry, Sangamon Taylor pulls off the most startling caper in Boston Harbor since the Tea Party. As he navigates this ecological thriller with hardboiled wit and the biggest outboard motor he can get his hands on, Taylor reveals himself as one of the last of the white-hatted good guys in a very toxic world.

The first time I read Snow Crash, the first time I'd even heard of Stephenson, I loved the action leading up to the end but thought it ended with a disappointing thud. Same with Diamond Age, same with Cryptonomicon... I read all of these before I had any connection to the internet memeplex around Stephenson. Anathem was a notable exception, with a nice proper denouement, and that was after I'd found out that lots of other people found Stephenson endings unsatisfying. I also didn't find fault with Zodiac or The Big U, although these were of course somewhat more conventional than his later works.
I don't think you understand why thousands of people find most of Stephenson's endings unsatisfying. That's fine for you. It does not mean that the rest of us are just making it up for the memes.
