So I asked someone about this and someone just asked me...so I thought I'd just briefly blog about it.
There's a widget called LinkWithin that you can put on your blog that at the end of your posts, picks three of your past similar posts and provides links.
Ok, it's obviously the end of the work day and I feel like I'm not making much sense, but you can check it out on my blog if you view it directly and not in a reader or whatever.
I don't know how they pick which posts to link to. Somtimes they are really relevant and sometimes not so much. But since I've been blogging for over TWO years now...it's kinda fun to see some of my older posts.
