Originally, I was going to capture people's emails for the waitlist. However, I realized two things:
People don't like giving out their emails.
I didn't want to pay for an email service.
So, I decided to have people simply follow the Twitter account, @GaryVeeFollowMe. @whitandersonIV of Bad Unicorn VC uses this tactic. I considered having people comment on a specific tweet, but the goal long-term is to get followers, so used Whit's approach instead.
