Well youtube knows this is cool for people who want to stream live action events. Its a nice new addition to the existing functionality.
I also like vimeo and dailymotion.
Also good sites.
But the streaming schtick is getting old and it needs something new.
When I was driving back home from Dresden I tuned in to this german business talkshow and they had a company named Kiiroo on. I think kiiroo wil stir up a storm next year because they claimed to have built a gadget that would let you touch people over the internet.
You could share intimacy on your pc lol. Cool for people in long distance relationships.
But just streaming might be a nice addition to youtube, it still isnt anything major or ground breaking.
