In a session last week on one of our Spanish teacher training courses, we were talking about using tools such as Edmodo or a Google+ Community or other social media — and the question was raised on what you should do if learners start sharing things that have nothing to do with what you've been doing in class.
My answer to the question would be "Brilliant!" — for two reasons: (1) that's exactly what I want to happen with shared digital spaces used with learners — I want them to take charge of running it, rather than me doing all the work; and (2) if it leads to more interaction and use of language, fantastic! That's why we're on social media with language learners!
An example would be the video above, shared by a learner in an Edmodo group being used by a colleague, Esther, who then shared it with me.
Here's another example, one I posted on Twitter the other day, which I shared with the teenagers I have in a small private class which meets only once a week, sometimes not even that — circumstances crying out for a digital space in which to share and comment on such things:
These things can be a bit hit-and-miss: I thought I'd got zero response (!) on this one, as none of them "replied", but face-to-face it turned out that they had all watched it and they found such a lot to say about it!
And while we're on the subject of great videos for class, here's another TED talk that looks great material if you teach adults B1 or above who spend any amount of time attending meetings:
You might try this generic activity with it, and then talk about whether or not they think the idea would work in their company and why/why not.
If you don't have a lot of learners doing that kind of job, it's still a brilliant one to share with them — both for the listening practice and for any discussion it might generate. It won't always do the latter but that's not going to stop me posting such stuff!

A class blog would also make a perfect platform for such things.
Next question: How do you correct all the errors learners then make?
