Applications for Education
Instablogg could be a good platform for having students publish their hyperlinked writing online. Instablogg doesn't require any personally identifying information so it is ideal for use with students under the age of 13. The one drawback to Instablogg is that the format is geared toward one-time uses rather than for creating an online portfolio. But if you're just looking to have students quickly publish their ideas and get feedback in the form of comments, Instablogg could be a very good option.
