Once bitten, twice shy?

An agency source recently told me that he's having trouble convincing clients to get on Twitter, because they still feel burned from Second Life. Mostly, the clients don't believe they have a sizable audience on Twitter, so they don't want to invest in another ghost town, he says.

I suppose this is the risk of being an early adopter, they'll be some misses. But I wonder if others have faced a similar problem: are your clients more skeptical of social media because of some misses, like Second Life?
