I came across a new open source commenting system today called HashOver.

The project was released earlier this week under the GNU Affero General Public License with the goal of being a self-hosted open source replacement for proprietary comment system services such as Disqus.

I personally think that Jacob Barkdull, HashOver's developer, definitely full-filled the goal he was striving for with his project.

Even as a newly released project, HashOver comes with everything that you would expect a mature comment system to have and it is very easy to implement into your existing website.

Features:

• Easily integrates with your website with one line of JavaScript or PHP.
• Light-weight and easily themeable
• Comment administration and Spam filtering (including referer checking and IP blocking).
• Comment sorting
• Comment permalinks and RSS feeds
• Threaded replies
• Email notification
• Avatar icons
• .. and more!
