What are some online trends or new ideas that are creating multimillionaire Internet entrepreneurs currently?

Seriously - none at all.
Any market that already exists has already been cornered.

People don't like paying for the internet so you have to find something that everyone uses so you can convince companies to advertise on the site.

I'm convinced that google and all that is connected with it is being heavily sponsored by the CIA. They can get data on every internet user in the world. That data is worth billions.

If anyone only knew what the next idea was they could become extremely rich.

It has to be something really stupid and banal like Facebook or twitter. The idea doesn't matter - convincing people to use it is the problem. Useful and sensible sites don't make money.

LOL - I love the way yahoo spelling checker refuses to understand "Facebook". Sour grapes I'd say.
