I'm not crazy about this. Will videos just automatically appear in my feed- and start playing? If they play with the volume up that's going to get irritating (and bandwidth heavy).

My reaction in general is the same as the tagging feature- I'd prefer it didn't have it, as I like Instagram as a service for almost taking abstract photos (landscapes, patterns) than of me and my friends on nights out. But I also realise that it is inevitable, what with them being owned by Facebook.
