I searched for TextTeaser and only found a boilerplate login site and some unrelated results. Have you or do you plan on posting the code anywhere? The results look very good, and though I'm sure you can think of some great uses for it (incl. ways to monetize it) it would be fantastic to have a good summarizer for personal notes and the like. I suppose if Readborg was a full-blown RSS reader (it doesn't appear to be) you could pump all your writing through an RSS feed but that's a sticky way of doing things.
Edit: Saw the comment below asking if we could see your thesis, which I would be very interested in especially if you don't plan on sharing all of your code.
