Isn't it redundant to summarize BBC articles? A bit off topic, but I do think it's a horrible way to demo your app considering that the BBC's online news outlet has been publishing articles that feature "paragraphs" which are rarely longer than a single sentence for years. In other words, summarized news. Still an interesting concept. Quite interesting that this idea has already been pointed out well over a year ago out by one HNer, Geee, via Open Text Summarizer. Makes you wonder what he's actually using to summarize the content.
