Guess what? You can now see the faces of those who are commenting on your Google Site. But let's be honest, how many of you are actually using the comments system in Google Sites? I haven't stressed this feature to my clients but perhaps now I'm a bit more proud of the commenting system at the footer of Google Sites pages.
You get portraits, a better looking design, and notification settings.
Tip: If you don't want the comments feature at the bottom of a specific page, go to More > Page Settings > Disable Comments.
This is a small feature upgrade, but perhaps it will allude to the much more demanded public commenting system people have been clamoring for. I mean, add public comments to your announcements so that it acts more like a blog. It's been difficult to integrate Disqus to Google Sites (can be done but looks pretty clunky). In the meantime, this is nice for those who are already using the editor/owner comments for improving their intranet. It's like leaving sticky notes for people to improve pages I think.
