Week 5 - Wikis .... Explore

I've had a quick look at the new Learning 2.0 wiki and ran through the pbwiki tour, now I'm just waiting for the invite key so I can go in and play. The thing that has struck me most this morning is that whilst each of the wikis I've looked at is essentially different they are also essentially the same so though the look of one is so different to another I feel reasonably confident about editing the Learning 2.0 pbwiki simply becasue I have already played around in Wikipedia and the Readers Advsiory wiki (which uses Wetpaint).
