Is YouTube Doomed?, Ctd.

Here's why YouTube is not doomed:

1. Storage costs are falling exponentially.  So while users keep adding content, the cost of storage is declining at an even faster rate. 
2. Older videos while still costing storage space, do not cost bandwidth because nobody is looking at them. 
   

If it ever became a problem, google could just start charging users who upload more than a certain amount.  Countless sites have policies like this and it would be pretty reasonable to do that.  So this would provide another way for Google to make money off of YouTube.
