Let's start with the bad news: Google Tasks doesn't offer any sharing functionality. At all.
It's frustrating because when you're collaborating, it's helpful to see the same list of tasks as your co-workers. Not offering collaboration sets Google Tasks apart from the best to do list apps...in a bad way.
But Google Tasks is still worth using. It's quick to access in the sidebar of Gmail, Google Calendar, and Google Docs, and a streamlined mobile app makes it always available when you're on the go.
You just can't share tasks. Happily, we've got a workaround, of sorts: You can send items from Google Tasks over to other to do list applications, then share them from there. It's not perfect, but it's the closest thing to sharing Google Tasks we've found.
