Suggestions for best sources on teaching with loosely coupled tools

So, if you’ll induldge me again, I have another question as a follow up to the last one.

What is your favourite source for finding new examples of people teaching online with loosely coupled tools? Is there a blogger you already follow who regularly posts great examples from the field? Or is there a trove of examples already identified that the rest of us might benefit from.

If you have specific examples to point to of people teaching with Web 2.0 tools or in a loosely coupled way, I would love to hear about those too, but right now I am trying to gather regular sources/feeds, people who regularly note best practice examples. Suggestions truly welcome – SWL
