It is easy to create interactive and attractive timelines. Sharing them is extremely easy, in Web 2.0 style with tools such as:

TimeToast

TimeRime

I understand and am totally fascinated with the idea of sharing content online (quality user-generated content) and the big shift this brings to learning. However, I see college students using this for assignments and they might need a hard copy of their work as well. 

So, I would like to suggest either a PDF convert functionality or a “print this timeline” option (printer friendly version). In case I’d like to publish the timeline both online and share but also needed for a project and so on.
