My previous post was posted with Google Sidekick. I tried it before, but didn't push those 'sidenotes' to my blog. Now I've done it a first time, I'm planning on doing it more often.
Google Sidekick reminds me of Trailfire. I used to use that tool. The problem was it wasn't used by many of my friends. But it worked nicely. In the meantime Trailfire was discontinued. Google Sidekick will take it over from there.
