Should I write a blog post for each Daily Create I do?
The Daily Create was intended to be something that can be done quickly, and ideally, something that focuses more in composing an idea than editing. Therefor, the only requirement for Daily Creates is posting them in the distributed media sites (flickr, YouTube, and SoundCloud).
That said, if you are compelled to tell the world something more about your creation, or if you wish to gather comments on your site, by all means blog them.
For our in class students who have a specific requirements for doing Daily Creates, we suggest that rather than blogging individually, to do as a weekly wrap up summarizing all of their Daily Create activities for a week. In any blog post, you should embed the media, not just link to it.
