The blessing and the curse of the Web are hyperlinks. When you click on a link, it could take you anywhere, from a product page to the website of the creepy old puppet store down the street. The result is a loss of context.

Takeaway: Abrupt changes in an interface are hard for users to process. Don’t leave them in the dark; always show what’s happening.
