Marcin from SEOprotoolz just emailed me about a couple new niche finding updates he added to his blog. I REALLY like these too! The 1st one uses some CJ data. The 2nd one is really helpful after you find your niche to determine good sought-after key phrases and potential subject lines for your articles or pages.
From Marcin:
"As you mentioned one of my articles in your blog (on discovering profitable niches in under 10 minutes, using wikipedia and google's keyword tool), I thought you could also be interested in the two follow-up articles that I wrote about this topic.
In the first one, the method is still pretty much automated, but gives the marketer much more control over the final outcome."

"The second method requires more manual work, but can give you excellent insight into what people really want to know."
