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.

11 Incredible Dividend Stocks
The Motley Fool embarked on a mission this week to educate investors about why overlooking dividends is a big mistake. "Forget Folgers; dividend investors know the best part of waking up is knowing that the companies they own are sharing their profits through cash payouts," wrote Fool contributor Matt Koppenheffer in the introductory article.

The mission to uncover 11 incredible dividend stocks kicked off with classics Wal-Mart (NYSE: WMT) and PepsiCo (NYSE: PEP) and international powerhouse Philip Morris International (NYSE: PM). Follow the link above to see the introductory article and get the full rundown.

Searching for a Better Index
Fool columnist Morgan Housel says investors might be surprised that "
most index funds aren't as passive as they might think." The SPDR S&P 500 (NYSE: SPY), for instance, weights its holdings based on the companies' market caps. Morgan did a little math and points out, among other things, that "ExxonMobil (NYSE: XOM) alone currently has a higher weighting than the bottom 100 companies. … It's more of a 200-company index with some negligible scraps of another 300 companies thrown in."

If you're not comfortable with the SPDR formula, read Morgan's article for a peek at so-called fundamental indexes, which "periodically rebalance so the cheapest companies based on metrics like price-to-earnings or price-to-book hold the highest weightings." As Morgan notes: " If an index is going to select for a certain quality, why make it size? Why not value?"

2 Stocks to Buy and 2 Stocks to Sell in Social Networking
Facebook members have a couple of things to do today: (1) "friend" and "like" The Motley Fool and (2) read longtime Fool contributor Rick Munarriz's thoughts on stocks to buy and stocks to sell in social networking.

"Social networking isn't hot," Rick wrote. "It's a sticky yet difficult-to-monetize niche. Facebook is the company that will command a market cap in the tens of billions when it goes public in the next year or two, but what's an investor to do until the IPO arrives?"

Check out Rick's article to get his answer to this question and to read his thoughts on Google, T. Rowe Price, Quepasa (AMEX: QPSA), and Renren (NYSE: RENN).
