Box.net - Free Online Storage

A pretty good network storage space, with 1G of free space, and a single file limited to 10MB in size. It utilizes AJAX technology, has a clean and attractive appearance, and its operations are very user-friendly - almost all functions can be completed with a single click. It supports tag functionality, multiple methods for uploading and downloading files, and allows you to set sharing options. There are also some web 2.0-based features such as RSS output functionality. The upload speed is also quite decent; I tested it and the average upload speed was around 70k/s. If anyone's interested, you can register and give it a try.
