During the week, our Motley Fool Twitter feed (@themotleyfool) shares lots of articles. In case you missed it, here are the five most popular articles that were tweeted this week.

1. @TheMotleyFool : Our own @brianlrichards visited #OccupyWallStreet last week. Here are the 3 smartest things he heard there: http://mot.ly/nZMkBR 

Two Fools headed to the Occupy Wall Street protests in New York. The movement itself has been gaining momentum in New York and throughout cities across the United States. In speaking with several of the protesters, a number of smart ideas emerged from articulate protesters.

Check out three smart arguments heard at Occupy Wall Street.

2. @TheMotleyFool: Yes, the market's looking mighty turbulent. But before you strap on the chute and bail out, consider this:  http://mot.ly/ntGSbu  

Given the domestic and international market turmoil, many investors might be thinking that the stock market will head lower. But with stock valuations at near-record lows and corporate profits at record highs, now is a great time to take a look at blue-chip stocks such as Berkshire Hathaway (NYSE: BRK-B) and Philip Morris (NYSE: PM).

See why you should be investing in blue chips despite the market mayhem.

3. @TheMotleyFool: This company lays claim to 6M net oz. of silver -- but it's not a miner. Meet the world's weirdest silver stock:  http://mot.ly/rqpKGA

Weird but also fascinating, this company hunts for treasure. Odyssey Marine Exploration (Nasdaq: OMEX) recently discovered the remains of two sunken ships with large amounts of silver on board. With the current price of silver at roughly $32 per ounce, the value of the silver alone would be just 5% less than the company's market cap.

Immerse yourself in more information about this treasure hunter and see why it should be on your watchlist.

4. @TheMotleyFool: Time to dust off the old Mac vs. PC arguments?  @TMFpcmart03  on why Windows 8 could be the $AAPL iPad's biggest threat: http://mot.ly/oYCfkY 

It's no surprise that Apple (Nasdaq: AAPL) dominates the tablet market. But what is surprising is a new survey showing that 42% of U.S. consumers would prefer a tablet that ran on Microsoft (Nasdaq: MSFT) Windows. The same survey showed that consumers preferred a Windows or Apple's iOS platform over Google (Nasdaq: GOOG) Android. Could Windows have a future in the tablet market?

Will Windows 8 change the tablet market?  

5. @TheMotleyFool: But ... but what will we shamelessly mock now? How can you abandon us like this, Microsoft? $MSFT Zune, R.I.P.: http://mot.ly/qeRen3

First Microsoft discontinued its Zune player. Then it backtracked, saying that was a mistake. Then Microsoft confirmed once more that it's no longer producing Zune hardware. With Zune revenue on the decline, Microsoft will be able to refocus on its Windows Phone 7 and Windows 8.

Contrast the paths of the Zune and the iPod.
