How Web 2.0 reduces business over heads

It's striking coming through from many of the presentations is how Web 2.0 provides business tools at a cheap rate, Will Wynee from Arena Flowers makes several of these points especially around marketing...

• Marketing - You can spend alot of cash on Google Ad words but relative to traditional advertising it works at a wider variety of scales so more businesses can access far larger audience for less cash
• Content and knowledge management - What used to be IT systems that cost huge amounts for cash can now be bought off the shelf for free or a small monthly outlay
• Collaboration - working closely with people and orgs in other countries is expensive if you're flying people around the globe, if you can use web meetings/conferencing and wikis for co-production then this kind of international approach becomes accessible to small business and voluntary and community organiations.
