Over on the right of this blog there used to be a widget : What I am reading, which displayed a list of links to pieces that I had read and found interesting. I know that a lot of readers used it and clicked through the the things that I had highlighted. This was done through Google Reader - I'd see something I liked in the RSS feeds and click "Share".
Unfortunately, Google has removed that feature from Google Reader, so there is no longer any point in that widget. Sorry about that, I enjoyed using it. Google apparantly are trying to drive users to Google+ and this feature seemed to be one that they wanted in G+ rather than Reader. Unfortunate.
