Disqus (pronounced “discuss”) is a unified comment system for blogs (and my tumblelog). I’ve been playing with it on and off for a while now and I think I’ve finally made the decision to use Disqus as my main comment system.
Downsides
At first glance, it may seem like a no-brainer to go with Disqus, so why was I so hesitant to use it? Disqus easily drops into my blog and seamlessly replaces the comment system. It also opaquely lays on top of the comments that already exist in Wordpress’ comment system. For me, this is a critical behavior because I frequently re-read comments for reference. An import feature is on it’s way but it would be nice if Disqus just mirrored the comments out of my database via some control in the admin panel.

Another Disqus behavior that I don’t much care for is that when a comment is written into the Disqus system, it does not mirror back into my blog’s comment system which is being masked. If I, some time in the future, decide to not use Disqus anymore, all my comments will be lost (or backed up in a non-related XML file) and not stored along side the respective posts. Also, if I use Wordpress’ export feature, the comments will not be included in the backup with the posts.
- Disqus doesn’t import non-Disqus comments (yet).
- Disqus doesn’t mirror Disqus comments back into my blog’s database.
- Disqus mirrors my blog posts on it’s discussion page which may confuse users.
- Disqus doesn’t have a rich text editor for non tech-savvy users.
Upsides
So why am I using Disqus? The benefits far outweigh the downsides outlined above. I have 16 plugins (including Disqus) enabled on my Wordpress install. Five of those plugins (30%), the largest percentage of my plugins, are for the comment system! Disqus cleanly abstracts all that management (users, spam, moderation, reputation) away from my site while, at the same time, providing a much richer blogging community. Also, my blog and tumblelog can share the same comment system.
- Disqus cleans up comment management and “leaves it to someone else.”
- Disqus shares my sites’ comments.
- Disqus connects my comments to the rest of the web-wide blog community.
