It's time to turn that idea on its head.
Now, it may be that I'm just a F.O.S.S. junkie, but I tend to avoid software that has strong lock in because I know that I'm going to be trapped if it doesn't live up to the hype. So having lowered perceived stickiness will lower the barrier to entry.
Secondly, if I see a product with low barrier-to-exit and yet it is popular and clients renew and stick with it, I know the clients are staying for quality and not due to a technical lock-in. For me, that is the real stickiness.
When I talked to Damian (Hogan) about this last month, he agreed and expanded to say how true stickiness comes from providing a value proposition where it's worth more for clients to stay than to leave.
And when it comes to that kind of stickiness, we are very, very sticky.
