Free is great. But, if you really want someone to stay focused, you’ll want them to pay.
Ask yourself, why do you want to give away something? I can think of several reasons:
– You are generous
– You want someone specific to have it
– You want it to be available for everyone (equality)
On the other hand, if you give it away, people might not think of it as valuable. They’ll want it because it’s free, not for the value it represents.
Focus is attached to money (and/or energy). When the transaction of money is finished, the person will be more interested in what he just bought. It’s not necessary true that the more money he spend, the more focus he’ll have on the new “thing”. It’s not always like this, but more often than not. But, there has to be some cost involved for the person to want it and stay focused.
The best alternative might be either selling it for $1, giving it for free for a limited time, or giving a specific amount away for free. This way, some people will get it for free, but not all. They’ll understand that it’s valuable (and that it has a price, but that they’ll get it for free because they are early adapters). Paying $1 will force them to think before they act, even though it’s still a small amount.
