Forums: Discussions for entrepreneurs and small business.

Imagine that I have a magic parser that can parse discussion forums like this one and save this data in a huge DB in a structured way. It means there will be tables: forum, subject, post, etc., populated with data from forums. So I will have a kind of global storage of structured forum data. 

Now the question is how can I use it? Is there a way to earn money on this?

Here are some ideas:
1) a web site that allows users to browse information from hundreds of forums in one place in a unified way
2) set up a service that allows to subscribe updates from different forums at once.
3) just provide access to this database for other 3-d party companies or webmasters, SEO specialists.... will anyone need this?

Most of all I am curious about the last options...

What else?

Thank you.
