First Indication of Interest

I think it's been about a week since I first floated the idea of a class blog as a project.  It's taken a week until I've had any questions or interest shown.   The content suggests they think they'll be supporting me which makes me think I need to encourage them to dream bigger and realise they can drive this project!  I'm wanting to create a space of student authorship and ownership however perhaps I need to think of additional scaffolds.
