Thank you, this is really great stuff @eric!
Have tried it quickly and it's really simple to set up. Did a Twitter zap that posts a message when getting a new follower, including the amount of followers that person has.
The only bug (?) I've found: The message is sent from my account, not the username I specified in Zapier (which is optional)... Also, the user icon that is used is not the one I specified (a public url to a jpg).
Any ideas? Or is this due to the beta status? Anyway, thanks a lot!
