Zipcast is Slideshare’s newest tool that allows users to conduct a Web meeting while presenting online. Zipcast is built on the new Web Sockets feature of HTML 5. It runs fully in the browser using HTML5 technology and doesn’t require any downloads or proprietary software to run.  Users can give a voice-over and video presence to the presentation and to control when the slides change.  In addition, your audience can chat about the presentation in real time.  I think Zipcast is a great addition to Slideshare and it is a simple, free way to coordinate an online meeting.

Like Slideshare, it is free if you are conducting public meetings and do not mind for a few ads during the public meetings. The good thing is that the free version still allows for unlimited viewers. If want a private meeting without ads via password protection, you can purchase a Slideshare Pro account starting at US$19 per month.

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.
