A project funded by the Knight News Innovation Lab, Timeline works great with stories that have a strong chronological narrative. It does not work well for stories that need to jump around in the timeline.
With Storify, users can drag and drop content into a post.
With Timeline, users can either embed the code onto their website using JSON, or — if they don’t want to mess with any coding — they can fill in a ready-made Timeline template on Google Docs.
The project is currently hosted on GitHub, and users can find specific directions on how to both embed the code and use the Google Doc template there, too.
Future plans for the project include support of more media type, as well as iPhone compatibility, B.C. time support and better seconds and milliseconds support."
Here is the GDoc ready-made template: https://docs.google.com/previewtemplate?id=0AppSVxABhnltdEhzQjQ4MlpOaldjTmZLclQxQWFTOUE&mode=public&ndplr=1&pli=1#
