According to a Wall Street Journal article, roughly 60% of Netflix users watch only one show at a time. Another 25% stick solely to two. This means that only 15% of people watch three or more shows at a time, which surprises me, cause I'm like so part of that 15%.

Seeing as how TV shows are the most popular serials these days, this leads me to wonder. How do you guys read web serials? Do you have a bunch going at once, that you check whenever they get updated? Do you binge-read one serial, then move to the next? It also might be interesting to compare it to the way you watch TV (if you do watch TV), but that's totally optional.
