The old answer is, "Piece by piece" but I think I will add to that, "You've got to really want to eat it". You have to be motivated!
Today, amongst other things, I had an excellent one-to-one training session and all-round discussion on web & learning 2.0 with Jane Hart (click on the link to find her blog). At the end of it I felt that there was more in the world that I was ignorant of, not less. If you want a quick visual summary of social media applications out there, simply look at Harold Jarche's recent post. I have been introduced to Twitter, Ning, Moodle, PollDaddy and Jing... (Spike Milligan, "Ning nang nong" anyone?).
The "elephant" of social media is ever-expanding (although fortunately not infinite). This, I think, is the problem for those who have remained on the sidelines, those who say, "It's just too big" or "Yeah fascinating, but how are we going to make any money out of it?".
Many of the discussions on Tony's page recently have turned around whether people are developing new forms of learning; a brain 2.0 to accommodate all these new tools. I think that the bigger issue is motivation and fear of failure. Strangely, I find that my increased ignorance is motivating rather than demotivating. But perhaps that is because I am less concerned about making a fool of myself than when I was younger.
Perhaps the future for learning professionals is more one of cheerleader and performance coach than fount of all wisdom. To go back to one of my all time favourite quotes about learning from the 19th century polymath Wilhelm von Humboldt, "We cannot teach language, we can only create an environment in which language may be learnt"
Anyway, at Jane's suggestion I have lifted posting restrictions on my blog so you can post anonymously (makes it easier) and for those "lurkers" who would rather not, why don't you click on the poll?
