Social learning is like digging through a haystack looking for a needle. I spent a couple of hours on youtube last night and was amazed at what people think is worth putting up on a public website. Yes there is some great social comment there, but I haven't yet learnt how to use the search engine properly to filter out all the commercial promotions, (search on `mac'), personal navel gazing, one eyed fanatics, proud parents and so on.
My current learning curve is in trying to learn to use wikispaces, blogs, photo sites and video sites to best advantage in a learning exchange environment. Next week I might even try some personal vlogging - more personal navel gazing to upload to youtube - just to see how it works of course!

Learning exchange environment - what do you think of that to describe a new model of socially engaged learning?
