Is it advisable to creat a site to those high paying keywords? or maybe a blog to discuss those high paying keywords?

Oh goody! can't wait for yet another MFA splog.

Maybe a bit like the one in your signature.

I blame Google.. It's not hard for them to go through and ban adsense publishers that do this, but they make too much money from it, so they won't..

To get back to the question, just in case it was a genuine one, No it is not advisable to build websites around high paying keywords because those niches are oversubscribed to and are difficult to rank for.

Better to go for medium paying keywords and get a few clicks a day. It all adds up

yah! Its not advisable to create a site using those keyword. You'll going to have a hard time to make them rank in proper position.

yeah you can make a lot of cash if you can find cheap traffic...

Make a blog regarding high paying keywords, is much better.
