As all we are aware - an ideal e-commerce product (at least, one of them) is the one with instant delivery - software, for-fee sites, e-books. Do you happen to know any other products from this line?
Could you share your knowledge about similar cases you know?
For instance, recent 2-3 days I am obssessed with the idea of creating for-fee site - collection of jokes from all over the world (I realize it will take time and hard work before it would be possible to charge anything for the contents). But to tell the truth, I have no idea about the market, probably, there are hundreds of such sites.
What might be unique about my idea of joke collection website - to set contacts with contributors from as many countries as possible. Humor is different for every nation and that might be a really interesting resource. Entertainment always has some demand.
Would be great to learn anything from your experience/ knowledge and to hear your opinion about my idea.
I don't want to bring your idea down, but I don't believe it will work very well. I think it will be difficult to get poeple to pay for "jokes" when there is so much free content around.
If you want to stay with the "joke" idea why not make something funny that you can sell, like personalised cards for example? My wife always order these really funny birthday cards, where they use the real person's name and enter it in a funny context on the card. Maybe you can make something like that which is instantly downloadable...
