I set the default for this option to 50. If you would like to change it, you can do so from your options. Look half way down the options for "Number of Posts to Show Per Page". There is a drop-down that will allow you to adjust this from 5 to 200.

I updated this b/c I'm not a fan of having to go through multiple pages. I'd rather continue scrolling down. The default was 10 and I felt that was ridiculous.
