If your goal is to be acquired by Google, writing the app in Python won't hurt your chances as there is more resident knowledge of it (for front-end) than RoR in-house. This also has implications on the integration of the app with their product suite. On the flip side, depending on how complicated your app is, there is also a chance a Google engineer could reverse engineer and integrate it in their sleep (or 20% time) -- especially at the sensitive phase of growing the product. Perhaps some alternate questions: Which will get you to create your app as close to your initial version 0.1 in the least amount of time so you can test your assumptions about the market? Which community will you learn the most from and is the next logical step from where you are now as a developer? Which will reinforce core computing concepts with a decent framework to resist the temptation to give up out of sheer frustration?
