Freecycle.org - Great idea but where’s the web 2.0?

Freecycle.org is starting to gain more momentum. They are one of a number of online forums that facilitate the exchange of…well…..stuff — keeping all sorts of items out of landfills by providing an opportunity to give it away for free to someone else in your community. It’s a more efficient structure than leaving it on the sidewalk or having a garage sale. My question is… why are they still using Yahoo Groups as their primary means of interaction? This site is in dire need of some Web 2.0.

They are likely on a shoestring budget, therefore if you are willing to help them implement tags and their own online social apparatus, perhaps they would welcome the help.

Other than the obvious Craig’s List, what are your experiences with competitor sites that facilitate the exchange of goods and services? Which ones are most useful?
