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.<p>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.<p>The result is OnTargetEnglish.com which is growing and according to their recent FB post doing pretty well:<p>"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."<p>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.<p>Go get 'em entrepreneurs!
