There seems to be a bit of a theme happening in product launches this week with a number of services popping up to handle comments for blog engines. One of the more interesting and interactive ones was 3bubbles [ via TechCrunch ] – its just an EOI page.

What 3bubbles does is allow readers of a blog to to have a discussion interactively with other readers. The concept is certainly interesting and I think that its going to be a hit with major sites that have a lot of simultaneous traffic. For smaller sites like mine (I max out at about six requests per minute) there aren’t enough concurrent users for it to be useful.

This raises the question in my head – how are they going to make money out of this thing? Lets assume that only a small percentage of the blogosphere is going to use this thing, in order to recover the cost of development and operation they need to either charge the site owner a packet or perhaps even charge individual users to have the conversation.

Don’t get me wrong – I love the idea, and hope they do well, I just can’t see how to monetise it.
