Can you use ESP8266 With Raspberry Pi?

ESP8266 boards are pretty neat, but if you just bought one (And why wouldn’t you for only $5?) and have realized that you don’t have any obvious means (3.3V TTL USB serial device) to communicate with it, you can talk to it directly with a Raspberry Pi. Both use 3.3V signaling, so no level converting is required.
