The best way to spread the news about SFI and Tripleclicks is to teach people about both. Don't try to give them a sales pitch that'll just create rejection, because people have gone through a lot of sales pitches before.
Choose a product, subject or any part of SFI and educate yourself on that then when you feel confident that you can teach others about it just do it. All you have to have is to know a little bit more than your prospects.
