Now there's a heading! As you are no doubt aware, there is still no one definition regarding web 2.0, but let's not get hung up on that......Web 3.0 is here!
Whatever it is, there is a new Real Estate site in Australia which was apparently developed based on the principles of 3.0. I've been in and even listed my house (OK unit) as I wanted to get a handle on the sites functionality. From where I sit it does a good job of organising content so that it's difficult to separate the corporate from the UGC. Maps, photos, blogs etc are all integrated of course. It is absolutely a networking community ahead of a commercial site. But it seems to be aiming to achieve both. Not a great deal of content is up yet though so it could be some time until the experience comes to life.
Check it out:
On another note, it got me thinking that my mates who launched http://www.iambored.com.au/ are on to something. Maybe this site is 3.0 as well?
