I think Disqus is a great service, and I suspect that this business model will work fine for them, but it's obviously not ideal for everyone.

The economics of hosting comments are interesting -- there is real engineering effort in doing it well; there is product value to some degree of aggregation (spam & bot detection, etc.); the operating expenses are real especially at a Disqus-style scale, but it's not clear that many people would pay even a small subscription fee.

Makes me wonder about the viability of either a federated (not fully p2p, but "local" aggregators), either with or without actual coordination between members of the federation on spammers, e.g.. I'd probably swallow the cost of hosting comments for a few thousand "neighborly" sites, if it meant i had a good commenting system with no commercial interruptions, and be happy to subsidize "good people".
