Okay, I've voted and as I've mentioned before, I prefer to read fanfic in instalments.
The main reason is because It's just easier timewise for me to read a part of two everyday then it is for me to find the time to sit and read a long story.
I used to be able to use high speed printers from my previous job to print off completed fics. Then I could carry around a hard copy to read at my leisure just like I would a paperback. That was an ideal situation, but since I no longer have that option, and I sure as heck ain't going to spend my ink cartridges to print off stuff like Masques.
Since I read while online, it's just easier to read in smaller bites.
