A couple of hours ago we made an update to the site with 2 significant changes:
1. The site was widened by 120 pixels. As Simone explained in her blog post a couple of weeks ago, this is to accommodate wider, premium ads that we'll be serving via the HubPages Ad Program as part of our direct sales efforts with advertisers. You should see these wider ads in action next week when our first such sponsor, Drano Snake Plus, comes on line.
Part of the widening involved putting a gray, 1-pixel border around Hubs. This helps break up the white space that resulted in the widening (we didn't want to widen the Capsules themselves, since many Hubbers took great pains to format their Capsules relative to each other with the current width).
2. We rolled out the Google +1 button. As we had stated earlier, we wanted to wait until all Hubs were moved to subdomains before we did this, in order to not lose the visible count like we did with Facebook Likes.
I would like to sound a note of caution here. Please do not start +1ing your Hubs or other Hubs. Each +1 is tied to a specific Google account, and Google will likely be monitoring each account's pattern of +1s, and the quality of the sources that are +1ing your Hubs. Therefore, self-serving +1ing will probably only work to your own detriment. Don't forget that it's the same Google that drives the bulk of search traffic to your Hubs!
Please just allow readers who don't know you to do the +1ing of your Hubs... and the best way to do that is to publish only the best-quality Hubs. That way, the +1 button can help reinforce a genuine stream of traffic from Google to your high-quality Hubs.
