Which website niche would you say is most likely to fail? In my opinion, I think things that are very limited in their niche and information such as say a health blog or forum, would most likely fail being that there's only so much information that can be regurgitated over and over again, once you've read one or two health blogs, you've kinda read them all. That's just my opinion though. Which website/forum niche do you feel is most likely to fail?
