What do you find is your best PLN resource and why?

I find my diigo groups the best way to find good resources for teaching and learning. I also enjoy being able to be more subject specific with the English Companion ning. Another excellent resource is TES connect (UK). Finally twitter - with careful selection of those I follow has brought me consistent educational debate and resources. {With twitter I did find it more comfortable to require permission for people to follow me. It has made me feel less vulnerable to those who I do not want part of my network} These three things are probably my favorite. I guess that may be simply because I have found them the most useful. I have found some real gems.

Of course - time permitting - there are all my RSS feeds from individual teachers and other sites:)
