Title
auto-cut long entries on your friends page

Short, concise description of the idea
Have an option to cut long entries on your friends page with something like "cut for length"

Full description of the idea
Sometimes I forget to cut a long posting, or think a posting doesn't need a cut that my friends do. I'd like there to be a way to specify the largest size of post I want to see on my friends page, putting other entries behind an automatic cut.
An ordered list of benefits

• You could get rid of a lot of the "please cut" comments that come with long posts.

An ordered list of problems/issues involved

• You'd need a way to figure out the size of a post, which isn't trivial. I suspect it's a combination of word length and number of images, but that would have to be worked out.
