dumb question: Do you want to build a website or a business? Anyone can build websites, but a business is something different.
Additionally, assuming you want a business: Are you making this in tight collaboration with your direct business audience providing advice/feedback/etc?
Finally, why would it fail in 6 months - assuming you want a business?
+1 for: It is greaet because we can just paste a link into the slack chat and everyone can join immediately.
Fun as a project to learn something new. Why did you make it? If you're looking for business, did you talk to paying users of e.g. feedly.com/ ? It takes a lot of effort to build a better product.
To quickly scan/read things, I prefer a list instead of cards (like trello).
Just pricing...
Ok, in that case I'd make the landing page all about pricing.
I'd also think about if there aren't any other benefits your approach might have. Maybe having everything happen on my phone is a benefit in that I can mix the automated messages with personal ones.
Or that I can use the same phone number for taking calls, etc.
Sure, ask a bit more specific perhaps? Cool stuff, mostly here: hackerbuilding.nl/
