Another option is to work at a consultancy where you hop aboard a new customer project every 3-6 months. Approach every customer as an opportunity to do some resume-driven development and pick a bunch of untested new technologies to experiment with. Be sure to do at least a couple of presentations to tell everyone about the hottest new things you are doing to bring value to the customers. Leave the project once it slowly starts sinking and then just keep hopping from customer to customer. You will be far away once the sea water starts coming through the windows and the non-technical people directing these projects will never figure out what you did.

I have seen that this is one of the most efficient ways to advance your career especially in larger consultancy companies with hundreds or thousands of different customers.
