But possibly not quite so gifted with using fora? :)
The problem these days, with the proliferation of internet based teaching, is that of credibility. If you take any teaching qualification aimed at the business world, the first thing is always an introduction to establish credibilty - an opening remark that will show your students that you have the authority and knowledge to be at the front of the class (if you don't believe this, have a look at the instructor notes for any Microsoft Certified Teacher course). Many of the instructors on the interwebs have neither the field experience nor the teacher training to be effective, yet new 'instructional aids' - be they DVDs, books or online videos - crop up daily.
It is still possible to find a mentor and learn the old way, but because so much information is available at the click of a mouse, few people will make the effort to go beyond that and seek out someone from whom they will learn. For many it is the continuation of the 'no skill required, learn today' mentality that they assume that magic is something that can be learned in an evening and no extra work need be done.
One advantage of learning online is that geographical boundries are rendered obsolete - I can be sitting in Scotland and learn from someone in California or Sydney, which ten or fifteen years ago would have been prohibitavely expensive and time consuming.
If you do want to learn online, and it is possible, try to find someone with experience in both performing and teaching, and ideally recommended by someone you know and trust. Not every student can learn from every teacher - with one person you may 'click' and the learning process becomes a joy, with another you may get frustrated and make very little progress.
Take care, Ian
