Investing decisions are made from a mosaic of data, yet synthesizing what matters can be tough. Enter the Fool poll. We show you the Big Headlines, and you tell us what's factoring into your investing decisions and help your fellow Fools in the process.

Google (Nasdaq: GOOG) had a rough week. Shares of the search king closed down more than 8% on Friday, mostly because of a minuscule first-quarter earnings shortfall reported the night before. Analysts were expecting $8.13 in adjusted earnings per share; Google delivered $8.08 a share.

My friend and Motley Fool Rule Breakers colleague Rick Munarriz has all the details of the quarter. Go ahead and read his take and then come back. Don't worry; I'll wait.

Notice the higher expenses? New CEO Larry Page authorized a 55% increase in research and development, sales and marketing, and administrative expenses during the quarter. Revenue rose by only 27% over the same period. Page and his team are investing in social technology to take on Facebook.

Over at, Scott Moritz writes as if this is a problem for investors to get worried about. "With previous chief Eric Schmidt, there was a comfort that shareholders' interests were a priority," Moritz wrote. "With Page, an engineer and product champion, the shareholder may have to take a back seat."

Really? I'm not so sure. Facebook is growing fast (and profitably) precisely because Google has failed to figure out social search. Page aims to change that. He's tied employee bonuses to success with social efforts. He's backed projects for adding social relevance to search results, including the +1 social search tool and rumored "Circles" network. And he's boosting R&D to develop similar offerings. 

At the same time, he appears unwilling to cut costs for fighting off Microsoft and Yahoo!, both of which are going after The Big G's core Web search business. Page has good reason to hold firm. New data from the Interactive Advertising Bureau shows that overall Internet advertising grew 15% to $26 billion in 2010. Search ads accounted for 46% of revenue.

So even though I can appreciate that change creates risk, shouldn't shareholders be thrilled that Google is investing to win in its biggest markets? You tell us. Please vote in the poll below and then leave a comment to let us know whether you'd buy shares of Google at current prices.
