You can bring on the first page or any other page, for the new visitors, the old content.It’s no need of the question why should I do this because you want that your visitors could have in their view your older articles.
What does this plugin bring new?
Other plug-ins are already doing a great job about random posts, but for me was not important to show just a list of a few links to my articles; not just a random generated list, with some titles. For some new visitors, the article’s content is more important than the title, actually, for anybody this statement is true . 
So, I created this plugin to mark out even some text from the random article.

Tired of boring lists of recent posts?
Taking advantage of the date to color algorithm used in the <a href="http://www.ikirudesign.com/themes/kaleidoscope/" title="Homepage for the Kaleidoscope WordPress theme" rel="nofollow ugc">Kaleidoscope theme</a>, the Mini Quilt plugin provides a more colorful way of presenting your recent (or random) posts. It also provides–by virtue of the carefully selected color–your readers with implicit information about when those posts were written. Your widgetized areas have never been so good at letting your visitors know what other wonders your blog offers.

Mini Quilt

For drawing attention to your posts in the sidebar. It uses a colorful way of presenting posts (what we call quilts) as sidebar elements.
