Google Reader has a sharing feature where they let you mark feed items for sharing. Those shared items are available both in a shared items page (which has a feed of its own) and in a "clip" you can embed in a page.
I am going to give the clip a try on this blog. Initially I am going to share stuff that both readers of my personal blog and this blog might like. If comment that they actually find it interesting I will put the effort into tagging the shared items so that only pertinent entries show up on this blog (unless of course people like seeing the few non-technical items I flag for sharing). Just add a comment to this blog entry if you actually like the feature.
