Excerpt length bug

Maybe more to the point is this: I’m trying to display the content of two random posts side by side on the front page, so that when the page is refreshed (or one of the posts is clicked, which refreshes the page) a new pair of random posts appears in their place.

Post Tiles seems to be an image-oriented plugin, but it’s so darn useful, couldn’t it be adapted to this use? If so, that would be a tremendous help to me.
