BlogSpot is banned at work, but is this similar to the 'Getting British Business Online' ( http://www.gbbo.co.uk/ ) thing in the UK? Hmmm, I suppose not, as GBBO seems to be a partnership offer. Still, I think more people should be aware of it :)
Google Sites was never intended to be used for external sites, and the sites are both difficult to navigate for the user and difficult to maintain for the company.
The only redeeming factor of GBBO was the free .co.uk domain name, but that only saved local businesses around £10.
