That's fine... my point was that temporary businesses/platforms can provide you the assets (exposure/cash/partnerships) needed to launch your sustainable, reliable income.
I'm not sure why you are arguing with me. I have stated what I am interested in when in comes to building a new business.
I am not looking for exposure, cash or partnerships -- those aren't the problem at all -- but I am looking for sustainable, trustworthy, long-term business ideas.
I have no problem building a business on another business' API's, but based on the track record of doing so, and your comments about them being temporary by nature, I think I will stay away from them.
