Fools were out and about this week in an investing world jampacked with actions and ideas. Here are three articles you might find useful as you decide how to invest your money.

Let Google Be Your Agent
Fool contributor Rick Munarriz went beyond the obvious in explaining why it was smart for Google's YouTube to acquire Next New Networks. "Between its advertising network, distribution channels, audience development, and branding initiatives, Next New Networks offers the tools for content creators to stand out," Rick wrote. YouTube is "essentially buying a minor-league farm-club system complete with talent scouts, coaches, and media reps."

See the article to read all of Rick's reasoning, and then scroll down to the comments section to get the conversation started on whether you think YouTube should be buying content or content enablers like Next New Networks. Feel free to leave a link to any YouTube video involving stocks, sneezing pandas, Ben Bernanke, and laughing babies.

4 Companies With Tomorrow's Fuel
Like many investors, Fool contributor Travis Hoium has taken note of rising gas prices and the ongoing turmoil in the Middle East and decided that it's time to take a look at how to invest in alternative fuels. Travis goes over the prospects of four companies: Clean Energy Fuels (Nasdaq: CLNE), Fuel Systems Solutions (Nasdaq: FSYS), Rentech (AMEX: RTK), and FuelCell Energy (Nasdaq: FCEL).

Clean Energy Fuels provides a network of natural-gas fueling stations, and Fuel Systems Solutions has technology that turns gasoline-burning devices into natural-gas-powered machines. Read the article to learn more about all four companies, and then scroll down to the comments section to see whether you agree with CAPS All-Star pstoimenov, who starts out saying: "In my humble opinion none of these companies stands a chance to make money. Anybody interested in alternative fuels should brush up their chemistry and study what these companies do."

Toyota's Latest Plan for World Domination
With General Motors (NYSE: GM) and Ford (NYSE: F) ahead of it in recent U.S. sales standings, a "smarter, humbler" Toyota (NYSE: TM) needs to step up its game, said Fool contributor John Rosevear, who this week reported on the new Toyota Global Vision. Emerging markets are key to the 10-year vision. "Despite the damage the brand has taken in the U.S., Toyota still has a worldwide reputation for reliability and durability, attributes that have given the company substantial street cred in India and elsewhere," John wrote.

Check out the article to read more about the automakers and how Toyota plans to use the Etios, a simple, fuel-efficient sedan that sells for around $10,000 and is the first Toyota designed specifically for the Indian market.
