The other key feature I'm curious about w/ Disqus alternatives is spam filter performance. Isso does not have any besides manual curation of comments.
Unfortunately this also rolls over to the spam filter portion. There were discussions in the bug tracker about this a while back, where the main Isso dev stated that it's a mostly obscure piece of software and spammers are not currently targeting it, so why bother worrying...
Scaling it horizontally is where is starts to get tricky.

You can see the demo-page here:
Provide your email address as an image, receive the comments in your inbox, append the really interesting ones to your blog article.
You really want to remove the spam and will have to do some moderation in order to keep your comments feed clean and interesting anyway. Making it a bit more difficult for your readers to comment has the advantageous effect that they'll think twice before writing. Moreover it also changes the way they write, because now they are addressing to a specific person instead of talking to everyone.
For sure it will probably drastically reduce the number of comments you get, but which one do you prefer: quantity or quality?
