The short answer has to be a firm “no”. When I started running webinars* over three years ago now, it was never my intention to usurp the important role played by training and information sessions in a classroom, seminar room or conference setting. Nothing can replace the immediate interaction with the speaker, the lunchtime chats with colleagues, or that exchange of views (and business cards) over a coffee at break-time.
And remember: "It's what we learn after we know it all that really counts." (Quips and Quotes by E.C. McKenzie ).
