In reply to Jason Lemieux.

I'm going to agree 100% with Jason. I'm currently running a hybrid of wpDiscuz with Postmatic, and my engagement level has increased exponentially since implementation.

I put this down to two reasons:

1. Lack of barrier to entry when commenting with wpDiscuz - you simply use your name and email, boom - done. It's also a very clean and simple UI, both front-end and back-end.

2. The simplicity of getting a new blog post by email, then hitting "Reply" on that email to leave a comment? And then get further comments and replies by email, and replying to those by email? Again, much like wpDiscuz - boom, for simple UI and ease of implementation.

It's early days, but in the month since I've been using the combo, my comments have probably doubled (and even tripled in some cases). Which makes sense - given email is still the most used channel for interaction, why would you not want to comment on blog posts and discussions from there?
