If your blog is hosted (for free) on WordPress.com, you may have noticed the Related Posts feature over the last 2 months or so. This sits at the bottom of your post, above the comment box. It links to as many as 4 other posts, on your blog and others, that are similar to "this one". The idea is that readers enjoying a post, might enjoy some others like it.

These are "real," SEF links. They go out, and come in.

With that said, I'll leave the discussion to the group.

i have a blog there i did sometime back and not maintaining that much. while linking to 4 relevant posts is a nice idea, i however dont link them directing my visitors to other blogs. if all 4 related posts are on my own blog, i dont have any problem with it.
