Starting today, we are discontinuing Powered by Redstone on the Google Currents platform. The reason for this is simple - no one uses it. Literally. Not a single living person has opened our Currents issue since February. We didn't advertise it much, but even when we did it only achieved about 20 subscriptions at it's highest point. I don't think anyone will miss it, and with all of the recent changes that required CSS rewrites, I sure won't.
Current subscribers will see the issue removed from their subscription list today. This is one of the changes we are implementing to create a more unified Powered by Redstone experience, and there are more to come.
