It's nice to see how exciting the possibilities are. In my particular case though - and this definitely skews my view - there are zero of these around me (Amsterdam), and the app does not even makes a mention of bots. Of course I can google "messenger bots" but thats not what I mean by discovery.

I'm sure there are hundreds of useful information-based services that don't depend on links to physical storefronts.

OTOH I can see why FB would intentionally not build that to avoid a flood of frivolous bots and provide more meaningful first experiences.
