"Read more" on long wall-posts

Once wall-posts exceed 10 lines, it would be nice to have a “read more” button. Thus, only the first ten lines of the wall-post would be featured on the wall. The same would apply to its comments, maybe even with a lower limit?

Clicking the “read more” button would take you to the page of that wall-post.

I've been seeing a lot of long wall-posts lately that are irrelevant to me. This would make the scrolling experience much better without any harsh measures such as deleting friends (I like my friends).
