For the several weeks Words with Friends on Android has been showing me nonstop ads for Trulia’s Android app. Someone at Zillow must have been paying attention because now I’m getting nonstop ads for Zillow’s Android app. Sometimes it’s not a bad idea to take a page out of the competitions book; now Words with Friends players know about both Trulia’s and Zillow’s app.

Is Zillow “stealing”? I don’t think so. Trulia and Zillow are just advertising via the same medium. Google’s not “stealing” from Microsoft when it runs commercials on TV just because Microsoft did so first. What do you think?
