Wikidot has just released announced that they are developing a new version of their home page which furthers their goal of making a social network of Wikis/websites. Furthermore, it's similar to iGoogle or Netvibes so you can customise it with widgets. This is certainly an interesting development. This makes it more attractive for someone to hold a Wikidot account, much like how everyone has an e-mail or blog or Facebook account now.
I've often thought of wikis as social club where users can add info and discuss their favourite subject like comics or computer games. I think this only makes wikis even more integrated with our digital lives.
