Schnack works, mostly, and let me comment on my blog using this account. But it has a giant assumption baked in: you will run your blog on one domain, and you will run Schnack on a subdomain of that same domain. My blog is at gdorn.mydomain.com/blog and I'm using an Apache Location clause to send gdorn.mydomain.com/schnack to, well, schnack.
So I'm forking it to remove this assumption or at least allow it to be overridden.
Because I don't have enough projects going already.
