I won't tell you where they going. But I know the more people will pin unique, cool photos they stumbled upon, the more artists, photographers and content owners will demand either their share, or take down.

In this another debate of "is this a bubble", something interesting came to my mind. I thing the issue here is that any online real estate that made it big, made it huge because they used the latest technology available. Think YouTube. When it started, barely anyone knew how to program flash and have a container to upload 5MB file and it could be coded in different movie codecs and youtube would read it anyways. This was definitely pushing the envelope! The technology was new, but it let you display videos and thats what counted. I think with the new technology coming in, like HTML5, etc, there will be new websites coming out and grabbing huge audience based on this new technology. So in other words, whomever is betting $1,500 millions on Pinterest, is like betting that nothing new will be invented over the web. This is like buying GeoCites, because nobody is sitting in garage developing WordPress 1.0. On buying MySpace because there is no Facebook. I hope you get my drift...
