Like all things, it depends. Certain features/abstractions have more value at different stages of an application.

I LOVE using views early on in a new application's schema as it allows me to evolve the logical model separately from the physical model, and once I've coalesced on something I like it's easy enough to swap the view with a real table and my application code higher in the stack is none the wiser.

Even Facebook at one point relied on MySQL triggers to keep its memcache fleet synced.

Views aren’t quite as bad as stored procedures. I could see doing a view being decently easy to manage - you can always add s column without breaking backwards compatibility. But you can’t imaging the number of times I’ve seen things like...

SaveCustomer_1 SaveCustomer_2 SaveCustomer_3

And you never know whose using what.
