Facebook comments
At KV Sites, we are constantly improving our main product, the WebME CMS. We originally built the system with a custom comments engine for the blogs, but have decided to use Facebook's comments engine instead.
What this means, is that when you add your Facebook AppID to your blog page's options, your readers will be able to post comments on your site while logged into facebook. This has the added advantage that their posts will also be visible to their friends, driving more traffic to your website.
