I am at TCEA again and in a workshop with the fabulous Tammy W. Tang http://tammyworcester.com/ As always she allows me to expand my knowledge. Today she is talking about using Blogger for student portfolios. I can see this, especially since Blogger changed some security settings, and students can now turn their blog off so that it is not searchable.
I also think Evernote could be used as a portfolio as well. Pictures could be taken of products and kept inside of Evernote. The searchability (is that a word?) of Evernote is awesome.
