Google, Youtube and my other thoughts

Well as you probably heard by now, Google has bought youtube for a 1billion.  Wow! thats a lot of dough.  Web 2.0 seems to be very big business.  Now you know why I’m trying to get into it.  I hear that yahoo is trying to buy facebook for 1.6 billion.  Well I wonder how users of youtube are going to react.  I feel that there will be some type of backlash, expecially if Google changes any of the features.  Which could very well happen with all the copyright issues that youtube will soon face.  But all in all it looks like a good move for both sides, the owners of youtube are rich and have Google to help with copyright issues and Google now has a foothold in the file sharing industry.  Now, why Yahoo would spend a bil on facebook seems a little strange to me. I mean, yes facebook has a lot of members, but how is it worth 1.6 billion?
