BookSuggest, in its web-app form, was the only way I could think of to use my existing technology in a way that wasn't, well... spammy. http://www.charleshooper.net/twitter/
The question I face now is: How do I take this application and deliver it to the user?
I'd suggest selling 'monetization made easy' movable type and wordpress plugins.
Just an idea; but it might make you money, and it wouldn't be spammy.
but that's the angle I would take. I mean, not only bloggers, but everyone who has content and users who wants an easy way to monetize.
hell, if you had an affiiate account with more than one bookseller, you could even choose the best deal (either the lowest price, or the highest commission, maybe chooseable by your blogger?) then take your cut before the blogger sees it...
Yeah... that's your freemium model. Give away a plugin that does it but with your affiliate id... give the blogger 50% or something. Then, for a higher fee, offer the plugin with the bloggers affiliate id, where they'd get the money direct from the affiliates, without you taking a cut.
Part of the challenge is maintaining a large enough corpus/histogram to generate good results. Meaning, I'd probably have to host an accessible corpus interface (or make one downloadable) as part of this project. But maybe that's where the dollars come in?
On the other hand, it's a kind of cool service, as an "enrichment" to twitter messages. If you could find some way of doing it for those who might find it useful without forcing it upon those who don't, I think this could be a great opportunity.
