In the immortal words of Cave Johnson, "Why not?!" :-) Dealing with structured data is easy compared to unstructured data, but there is a vast wealth of unstructured content just waiting to be tapped. I suspect there is so much interest BECAUSE TextMinr seems like a tool to explore a topic most folks find difficult to grasp. I'm a search engine architect and it's not a "solved" issue by any means. I think there is a lot of curiosity and a lot of untapped content that has yet to be leveraged. I'm certainly interested. :)
