A free service called Gogobot makes it easier to tap people in your social networks for travel recommendations. After creating a profile page on Gogobot.com, you can post questions about your trip directly to your Facebook and Twitter accounts. Responses appear in one feed on Gogobot, which automatically generates related photos, maps, and links. Then, you can choose which tips to add to your trip plan. Gogobot, which is currently in beta, plans to launch an Android app this year.
