i tend to, like most people it seems. To read some. Though most cases i don't bother. I tend to be very picky on what i read, so when it comes down to it. If i'm interested but i know my character in mind wouldn't fit i try to change it around while reading interactions. Though in the end i just stop. As for the ending becoming a cliff hanger. It doesn't bother me at all.

Other then that, it's also to look to see who i may possibly want to rp with.
