What kind of return data would interest you?

Make Fucking Badass Just Fucking Do It Now API (FBJFDINAPI for short);

If I supply a string of text for a task, I need its ID.

Given an ID, I need the time remaining on the timer.

When the time reaches 0 on a given ID, I need a message to display to my users.

Definitely putting this into v2!

When I fail to do something within the allotted time - I would love to see:

    {
        "my_custom_task_name": {
            "task_id": 124575,
            "result": "FUCK_YOU",
            "reason": "Time limit void"
        }
    }

But how would it return this JSON to you? Through a callback URL specified?

Yeah, that's what I had in mind. So if you POST this to a particular URL, I can probably do something - Send a text to my phone or send myself an E-mail, etc..

Edit: And please ignore the other comments asking you to stop with the profanity, etc. Clearly, those people aren't your target audience, but we are. If anyone feels offended, I think it's fair they don't use your service at all, than complain about it...
