Introducing our guest blogger

Please welcome Jia Lynn Yang, guest Post Tech blogger for the week.

I'll be out of the office this week -- doing some play, some work. But Post Tech readers will be in very good hands with Jia Lynn, who covers corporate policy for us. She can be reached at yangjl@washpost.com.

Thank you Jia Lynn. And thanks again, readers, for making Post Tech such a blast.
