Way back in the age of the dinosaurs, when I was in high school, I often had upwards of 15 threads at a time. Roleplaying and art were my only hobbies outside school and work. Being young and invincible, I opted to stay up till the wee hours of the morning almost every night so I could get more writing in.

These days, I max out at around 8--my games run at very different paces, so I am usually able to reply fairly to them.
