By webinars I assume you mean web conferencing? i.e people can talk and see each other at the same time?
I use them quite a lot of software demonstrations etc and find them very useful. There is loads of different software out there that can help you do this.
I think it's the way things are going. You no longer have to travel around the country to have meeting etc. It can all be done sitting at your desk and having multiple people all dialling in. It saves everyone loads of time as well
I used gotomeeting for the first time ever today to chat to a colleague based in Stoke who is part of our compliance team. I have to say it did work really well and we were able to share a screen etc. I can certainly see the appeal of this going forward.
Imagine having customers chatting to you via web conference
I do kinda miss the old days of schmoozing and networking in person. . . takes a little away from the personal side of bugsiness. On the other hand web conferencing is a lot more cost effective and saves you the time and headaches of so much travel.
I've registered for a few webinars where the instructor's screen and his voice were the teaching aids. The session was opened up at the end for questions, but the participants couldn't see each other. Most useful were the streaming videos that were available for everyone after the event, so if you couldn't attend the live call, you didn't miss out. Also great to refer to if you did attend the call, but were swamped with the information!
