Zapier has about 1,000 integrations, more than any of their closest competitors and at a price that is far less than others in their space. What you've done here is great! The UX seems better than Zapier and the extensibility & community approach terrific. The key, though, is going to be adding integrations rapidly. I might also stress:

- Bulk actions. - Sync actions.

And support for other programming languages (eg. python)

Hope that helps.
