This year, Boston isn't just playing host to the Democratic National Convention: it's also hosting the 2004 World Science Fiction Convention. (No, they're not at the same time. NoreasCon, the SF con, isn't until the first week of September.)
So the helpful folks organizing NoreasCon have come up with a list of ways the SF con isn't like the Democratic con. With due respect to Patrick Nielsen Hayden, I thought the list was mildly amusing.
