It is way better to get a "Yes" or a "No" from a client or customer than it is to get a maybe. I personally have been on both sides of this and understand the issue of making a decision and trying to avoid risk.
In my current roll I am helping bring new ways to make information sharable and available via new/social media (SwineCast being an example). This is a "new" way to share stories; "new" in the sense that technology (sharing of content via RSS feeds, time shifted conversations via podcasts) is making it easier to produce a show and share it widely.
So when I heard (I use Audible to listen to books) this bit from Seth Godin's Small is the New Big about getting people to say yes or no, not maybe, I was all behind what he shared. It is better to get a yes or a no than a maybe. Think about those times when you suggested an idea and a "decision" maker said "maybe". Think about those times when you asked someone out and they responded with a "maybe" answer ("I'm busy this week" or "I have a lot of things to do").
