It has once again been a while since my last post, time goes quickly. Anyway, we've all known that with things online moving towards the simple ideas, it has long been thought that the sites that provide things that the masses want will be popular. In the case of YouTube and many others people are saying "Why didn't I think of that?"
Looking back it's easy to ask the question but it's not very productive. I'd spend my time trying to think of the next best thing to attract the attention of a big company so hopefully they'll buy it, but it's not as easy as it sounds else everyone would be doing it.
Good luck if that is what you're also trying to do and well done to the YouTube founders.
