Yesterday I "finished" the landing page and got Netlify forms hooked up so I can accept people on my waitlist.
Today I saw this tweet https://twitter.com/daviswbaer/status/1163438754687803392?s=12 and decided what the heck I'll respond.
I got a few replies with some feedback (all pretty positive), and then checked the forms that night and someone actually signed up! I was shocked, and now a bit terrified someone might actually want to pay me for this idea.
Now I guess if I'm gonna go for it, I should start posting on fb groups and pinterest to try to get more sign ups.
