Some guys I met at the UX-net meetup here in Oslo have started a cool new site for Mac-users which is sortof digg.com for Mac software. The site is called iUseThis.com - finally a normal name for a hot new web-app, not some nonsense name or changing some letters in a normal word like others. It has all the "web 2.0" features such as RSS, social network, tagging and more, but according Arne, one of the developers, their aim is not to be a "web 2.0" site, at least in terms of design and wording. I think it's a great idea and I am looking forward to their next project, which is similar.
