Mammoth is a bookmarking tool that seems to offer the key aspects of Evernote mixed with Tumblr. At its core Mammoth allows you to bookmark websites and save files onto boards in your account. You can add notes to each of the links and files that you add to your boards. Mammoth boards can be private or public. Public boards are organized in a linear fashion similar to that found in default Tumblr themes.
Mammoth could be used as a project management tool. To use it to manage projects create a board and share it privately with your collaborators. Then use the board to share notes and assign tasks to each other.
Applications for Education
Mammoth could be a good tool for creating digital portfolios. Students could use Mammoth to showcase examples of their best work in a nice linear layout. Students can use Mammoth to share their portfolios publicly or share them only with you where you can give them feedback.
There is certainly not a lack of bookmarking and blogging tools on the Internet. The nice think about that is that we can try all of the options until we find one that suits our needs. If you haven't found the perfect tool for you, give Mammoth a try.
