Earlier quoted context omitted.
It's also worth mentioning that your tasks apparently can get turned off. It happened to me when I had a Twitter account tied to an RSS feed where no updates were posted in a couple of days. Bam, task automatically shut down. It seemed a bit weird and was completely unexpected, so I probably wouldn't rely too much on it initially, until you have used it for a while.
Sorry to hear your task got turned off. You should have gotten a notice via email about it. We monitor tasks that have trouble running (in this case perhaps the feed was down?) and always make sure to ping the task owners about it when we turn them off.
From what you're saying, you did it as a service to me, the user, and not to yourselves to save resources, which is what the e-mail notification sounds like - which annoyed me a bit, I have to admit.
I'll give it a second shot and send you an e-mail when or if it happens again. :)
