Really it would just be to tinker with it and maybe have sort of "notes" or "micro posts" on my own personal blog. Any changes / adaptions I happen to make I would certainly open source as well (although my programming quality might not be as good as your current project for all I know...)

I looked into basic Twilio SMS setup very recently, but it looked like I would find myself heavily invested in their documentation just to spin up something like you've made.
