I know Self Development (SD) is not a niche or even a market segment is more like an complete industry, but I'm posting this with a legitimate question. Why some of the best all time offline books and programs (think Anthony Robbins) best sellers are in SD but every time I do some research into the various segments and niches within the industry online I don't see any good number places (forums, blogs etc.) that show me a lot of buying activity. What I have seen in Niche analyzing tools confirm this. Even the blogs are always the usual suspects (1-4 huge blogs) and maybe 1-2 forums. So here is the question:
Are people using the internet to congregate and or buy Self Development products and if so, where?
