What simpler use cases do you see? In my case, I'm the language guy this is targeted at and have no clue what most web devs would want this stuff for. Spam and text classification of some kind maybe? MAYBE certain kinds of named entity recognition?
Well you as a news-distributor could try to build a tagging-machine, something, that takes texts from a sports news agency for example and enriches it with meaningful tags/keywords, your data from your statistics-section (and so on), to later match other, related content, or match images, or anything like this. something, that you could transmit with the original texts, to make life easier for your customers, with sorting and managing these texts in an automatic fashion inside their content management systems.
[edit]
This coming from a text guy, who recently started down the path of python and is hooked ;-)
