We used to host all of our blogs with TypePad. We were happy with the service.
Until one day, they changed a setting — there was no way to export our images files. They were holding us hostage.
So we left for WordPress. It was a ton of work, but we felt like we had to leave. We weren’t going to get locked in even deeper.
Summary: TypePad was so worried about customers leaving that they got all defensive — and forced them to leave.
Trust your customers to stay for the right reasons, like a great product or great service. You can’t make them.
