From an analytical standpoint, Disqus latest update to their blog commenting system seems trivial, especially with competition heating up now that the 8oo lbs gorilla (i.e. Facebook comments) has entered the arena.
However once tried upon your site, bloggers may fall in love with this new feature (not to mention their readers as well).
With this new feature, Disqus generates preview thumbnails of any image URLs you’ve referenced in your comment. To view the original image, just click the preview thumbnail. We hope this will enhance the commenting experience by allowing commenters to express themselves visually.
Now, old-school Disqus users might recognize that we’ve always done this. The difference is we now download and present these images to you as you’re typing your comment. This means you can preview your images before submitting, or remove them if they prove too embarrassing or career-ending. (Official Disqus Blog)
Currently the feature (known as Disqus Images) only supports .png, .gif, .jpg/.jpeg images under 2 mb, and the company is thinking about adding support for video platforms (like YouTube) in the future.
In order to activate this feature bloggers will need to select the Houdini theme within their Disqus admin panel.
While Disqus Images may not appeal to everyone (especially bloggers who loathe readers pasting images within comment), it may help the startup survive against rivals like Facebook, as well as IntenseDebate.
