Many threads here on HN deal with folks trying to come up with a niche application/product/service, etc. Well, what you don't see is that there are many non-mainstream sites/niches that are doing pretty well.

Some friends of mine that are not technical in the sense of being developers came up with the idea of a TESOL website. They both teach English for a living and wanted to showcase that knowledge and help teach others.

The result is OnTargetEnglish.com which is growing and according to their recent FB post doing pretty well:

"July turned out to be a big month for OnTargetEnglish.com: Facebook fans hit 1,000, email opt-ins (our list) hit 10,000, and we had our biggest month of sales. We're looking forward to growing the site and expanding what we offer."

So although there are lots of English and language sites out there having a niche and doing it well plus having the credentials (along with lots of hard work) can pay off.

Go get 'em entrepreneurs!
