I've revisited my PLE document and updated some areas. It was useful to reflect on how my working practices have changed. Not just from April to now, but also from a year ago to now. The way I learn has been invigorated by my engagement with Web 2.0. Instead of reading academic journal and JISC documents intermittently, I now engage almost daily with the the latest Learning Technology news and opinion. I won't spell out for you which is better.
Overall, my core tools are Igoogle, googlereader, bloglines, delicious and blogger.
