Thank you for Airtable, I'm a big fan, especially of the Zapier integration. Lately there has been a lot of discussion on Hacker News about projects like Opps Daily [1] and Nugget [2], where people write in about some pain point they have in their daily job that might be solved by custom-built software. I get the impression that Airtable + Zapier could solve a lot of those use cases.
