lazyweb: trying to find a blog post with tips for how to design bots that interact over SMS
less "how to use the Twilio API" (that's easy), more "what state to store in the database, tips for designing state machines, how to keep it simple, etc”
@b0rk My tip after working for a company that sent out party invitations via SMS is to watch out for and guard against infinite reply loops. The easiest way to do that is probably to store a DB record for each SMS and add rate limiting added on outbound number.
Something like only 6 messages per minute and 20 per hour.
