Good post, thank you. Now:
> Pinterest: [...]
- how do you see them dealing with copyrights of content? I don't think they will make much of profit if are willing to share $ with photography owners. The majority of value in Pinterest's user experience is that its fresh and content is created (pinned) by other users, NOT by corporations. The moment you will see every other picture a picture of an Ikea Kettle (or desk, or anything else thats been uploaded as "promoted pin") that resembles in color, shape, etc to what you were looking for, entire experience will loose its cool and Pinterest will start to stink!
> Youtube: [...]
- this was a huge gamble from many perspectives and owners had amazing amount of luck. Due to copyright issues, some board members were pressed very hard to vote with for a buy, but were strongly against (sorry I cannot back this up, but I read it somewhere couple years ago). Further, Viacom shoot itself in the foot by uploading their own material, but during discovery it clearly came up that owners knew about copyright infringement (duh!) and were willing to "slow down" with taking content down to gain more attraction. Clearly, in # of users AND eventual exit, they benefit in huge way off of Viacom content. Again, they were extremely lucky and in the light of recent Kim DotCom case, even more lucky Mashable is not interviewing them in a jail cell. But AFAIK some court cases Goog vs Viacom are still pending. As of whether it will turn out to be a huge success, I think we still need to wait. People are social today like never before. Instagram you mentioned was bought because FB was afraid of its growing userbase. As we both know, YouTube is only a little bit social -- not as social as comparing Instagram to Flickr, for example. If the userbase of the next thing (video) of sites like viddly will keep growing, and at some point owners will tell Google "fuck off, we ain't selling!", I say YouTube will be screwed. Also, if you look even further in the future, it obviously won't be as cool as today, or 3 years ago. Its like with Caddilac - they are building amazing cars for 110 years now, but if you ask your son: do you want Caddilac or Honda, guess what he will say.
