This really could be a huge step for Twitch. Although I do think it'll be a waste if they just use the ClipMine technology elusively for Twitch . I hope they plan to expand this to amazon as well.
In the past people have always had to use tags and titles to direct viewers in the correct direction - with this new technology, twitch will be able to direct users based on what is IN the actual stream or video that they are watching. It helps users find what they are looking for and I can't wait to see what other companies do with similar technology - the obvious one being YouTube.
I really would not be surprised if this type of visual information translation starts to pop up everywhere and I'm even more surprised that we have not seen it already.
