Thank you! I appreciate the kind words.

Another big thing I've put on my todo list (in addition to a "Click Here to Try A Sample Video" button) is a section where you can rate the quality of the summarization out of 5 stars. That way I can go back and identify the videos that don't work well with the service and see what I can do to improve the quality of those summarizations.

Update: Done (with one item on that todo list)! I've added a 'Random' button that loads in a random URL (from the small set of 3 TED talks I posted elsewhere in this thread) so that it's easier to test the app out quickly.
