Gina asked in her comment about the Shared items feature in my sidebar. This is what I wrote to her, in case other people would like to know too:
The shared link is available when you use GoogleReader (like bloglines, it tells you when someone has posted something new, and has saved me heaps of time). So if you do use GoogleReader, beneath each post that comes up, there are a number of options at the bottom, one of which is “Share”. If you tick that, it becomes part of your Shared Items list. Then click on the Shared Items link at the top left of Google Reader. This will bring up a list of all your shared items (you get to set a maximum number) and then you click on the link “put a clip of your shared items”.
Just follow the instructions from there, easier if you use Blogger as there's a button to add your list to your blog, you can still tweak colors, etc. I hope that's clearer than mud!
