There are quite a few interesting new websites in the www which could be also of interest to you. WYP for example offers a unique community which gives users the opportunity to buy property.

Currently, one hectar of land costs € 9.95. It is limited to the virtual world, so there is no real ownership - but why not becoming a virtual landlord?
The community Mynesto makes it possible to promote your own interior designs. Publish your own appartment or house design or just interesting rooms you like very much.

Additionally, it could be also a source for inspiration and for developing new ideas. All interiors are ranked and can be commented by other users. Similar websites are Solebich and Zimmerschau. Those are mainly focussed on the German market but if anyone knows international sites which are comparable, feel free to tell us!
