Facebook's Comments Box plugin since it launch has been added to more than 50,000 websites. Facebook launches new features to help increase traffic, engagement, and the quality of comments on your sites.
Here're the new features added in today's upgrade:
Users can now access each comment by its permalink, allowing users to share and a respond to specific comments more easily. Comment notifications in the Facebook newsfeed also direct back to specific comments, which's awesome because the alternative is pretty disorienting.
- Comments API
Facebook is providing an API so site owners can search and rank their comments, like highlight interesting and popular comments, reward top commenters or segment comments around a specific topic, like Apple or startups.
- More social context in the newsfeed
Developers now also have the option of adding meta-tags to include more information about a story in commenters Facebook newsfeeds, including any images involved, title and description. Facebook holds that this optimization will increase click through because users will feel more drawn to specific stories.
- Darker color scheme
Facebook is also offering a darker color scheme for darker websites, so developers with darker sites don't have to have mismatched commenting systems.
- Hotmail accounts have been added as a third-party login option along with Aol and Yahoo.
Finally, Facebook will be upgrading all sites to the new version of the Comments Box on April 29th, 2011 to ensure that Facebook users have access to the latest version across the web. You can upgrade today by adding the 'migrated=1' parameter to your existing <fb:comments> tag. Please note that once upgraded, you cannot switch back.
Note: Upon upgrade, ordering of the comments will shift from chronological to showing the most socially-relevant comments first as described here. Also, that the upgraded version of Comments no longer supports custom CSS.
