So, hello! I have been doing Twitter and AdSense for some time now and its okayish. Now I am trying to move onto something a bit better. I have been thinking on giving users some super simple opt-in page with just an e-mail submit form and nothing else and some engaging tweet explaining why the fuck would I need their e-mail. I have never done anything like this before (e-mailing and opt-ins) as I though they are really hard in term of getting e-mails. What do you think how would average twitter user behave with this? Would he submit his e-mail and so on? Would simple opt-in page even work?
