Wow. This looks great. I loved Disqus when it first arrived as it gave static sites a way of having comments. Your product neatly fits the bill of giving us the ownership of the comments back.
I notice that the self hosting options use postgres only. Did you have any plans to expand upon that? (I use mysql mostly).
Right now, the code is tightly coupled with Postgres and it uses some Postgres-specific SQL stuff. But that said, I'll think about some kind of database abstraction layer and maybe even support SQLite. No promises right away though, haha.
Agreed – looks like a fantastic product!
Seconding the question about MySQL support. I use MySQL for everything. I don't want to add extra gigs of RAM to my VPS just to run an instance of PostgreSQL for Commento. Postgres is much slower than MySQL in simple applications and uses a lot more memory per connection. MySQL is also more popular and more people know how to use it and tune it properly. Postgres is probably more stable, but I don't care about that in a commenting app.

Keep up the great work!
