Raffling off houses seems to be a growing trend, both for non-profits and those affected by the current economy, so it's great to see folks thinking big.
The Yerba Buena Center for the Arts raffle, for example, lets entrants win either a new house (which I could use) or $1.8 million to invest in business(ha!). Anyway, as a proud citizen who perpetually plunders the milieu of SF, I like opportunities to give back.
Implications - In today's society, the gap between the rich and the poor continues to increase every day. Businesses that devote their efforts to shortening that gap and to provide a better quality of life for fellow citizens will portray themselves in a very favorable light.
