Web conferencing is one of the very important tools for e-learning. I am impressed with dimdim, the first free web meeting service based on the open source platform. dimdim is a browser-based web 2.0 service that allows users to share their desktop screen, show a slide presentation, share an application, as well as talk, listen, chat, and broadcast via webcam. In addition, dimdim provides free hosted service for small gatherings, to seminars with hundreds of attendees. The best part of dimdim is that attendees require no software to download or install to attend the Web meeting. However, my only disappointment of dimdim is that you must use Internet Explorer to access dimdim and you cannot use other browsers like Firefox and Opera. I hope the second version of dimdim will correct this weakness.
Below is a video clip in which DD Ganguly of dimdim explains the key features of dimdim.
Another video is created by Livia Iacolare of Robin Good’s MasterNewMedia. It gives a short demonstration of dimdim which is a Web 2.0 service integrating video, VoIP, text chat, screen and application sharing.
