You know, I started out nasty, then I changed it to helpful, but honestly, I'm a busy guy and so will just say that if your first question about affiliate marketing is whether to get SBI or Wealthy Affiliate, and you're asking that question here, you have the research skills of a cracked-up hooker, and are going to spend most of the time between now and when you give up acting like a cracked-up hooker, going from door to door alternating between looking for money to blow on bullshit, and looking for bullshit on which to blow money.
