This system has the potential to offer interactivity, since each page can have comments added by those selected to Collaborate. I was able to add links by simply copying from another website with the links embedded and I could designate that each link would open a new browser window which is what I prefer: the portfolio remains open so that when an artifact is opened, the reader can close the window and easily return to the portfolio, rather than using the Back button.There is no data management tool, to aggregate assessment data, although Google Spreadsheet could be used. Therefore, this tool would work for formative assessment (providing teacher and/or peer feedback on student work) but not for summative assessment. But the process for adding comments and feedback would need to be agreed upon with the approved collaborators within the system.
The major advantage of GoogleDocs is that it is a Web 2.0 tool, and universally available through a WWW browser. I found it fairly easy to use, although it helped that I knew how to edit HTML to fine tune the formatting. I tried to use the Google Spreadsheet to create the Portfolio-at-a-Glance matrix, since it was originally created in Excel. However, I could not easily create hyperlinks in the cells, and the links did not translate when I converted the Excel spreadsheet into Google. So, I converted the spreadsheet to HTML and pasted it into Edit HTML on a new page. A table is easy to edit in a GoogleDocs page. I also found it extremely easy to insert images on a page. I published another "How-To" page on using GoogleDocs to create an online portfolio.
