On the other hand, the Google employee who has answered here is Matt Cutts. I doubt many lesser-known employees at Google have the luxury of replying outside of official company forums and sites in such a manner.

From personal experience, finding an Apple employee who can even find out what is going on with an iPhone app waiting for review for months can be difficult if not impossible without connections inside the company. However, if you have a development-related question or a bug report you want looked at, there's plenty of Apple employees on Twitter that would be happy to answer such as Chris Espinosa (a manager on the Xcode team and Apple employee #8, @cdespinosa) and Michael Jurewitz (developer tools evangelist, @jurewitz).
