videos with no real time questions. :(

I was watching this user interface design video from google tech talk series: "Don't make me click".
After watching that I felt, as I was watch lot of these videos, what if i have some comment or question and I want to enjoy the video same as, as if I was there.

Can google provide me an interface to ask question on that very moment and do some NLP from comments on video and figure out my answer (like the concept of 1 player game and zero player game, prof. Luis von Ahn speaks about this in another tech talk)

Moreover when a video is more popular, comments are many which are most of the times containing much more pointers than original video. But, I don't see anybody providing an easy access to this gold mine. :(

Something from my past which connects to future.

I could remember the day very clear, as in my 3rd year of b.tech(around 2004), I found this research project making a chip based fan, I chose that as my topic of presentation for some thing as emerging technology. Today I saw an article on computerweb, mentioning about this technology being available now as a finished product, I feel some how happy! although I haven't done anything related to it.
