Can I have Sandy Update my twitter?

I think this is a very large idea. It's a good idea, but it's the tip of a much larger iceberg. What you really want is for Sandy to support user customizable ***actions***. Also, that these actions would take place in response to certain events.

As far as I can tell, Sandy doesn't actually "do" very much. I mean, she doesn't interact with the outside world very much. She sends email, she sends tweets, she sends sms messages, she reads incoming mail, tweets and sms messages. This is limited, and the nature of these communications is fixed. When Sandy sends a tweet, it is always sent as a direct message.

What you're suggesting is that Sandy be able to "log in" or have access to your Twitter account, and that she should have the power to change your Twitter status to reflect what was in a reminder. This includes 2 main things. 1) Sandy should be able to do some sort of action and interact with a Twitter account and cause it to be updated, and 2) that Sandy should do this action in response to an event (the time has come to go to the doctor.)

I think these are great ideas, but they're difficult. In order to do it correctly, Sandy would really have to support an API, or some sort of scripting. "Sandy, when 5 o'clock comes, I want you to do X." Where X could be anything.

Some examples:
Send this email to this address. (email and address are given to Sandy.)
Call this API and send this data. (API and data are provided)
Visit this website and log in. Then do another actions. (website and password are provided, etc)
etc, etc.
