NEW YORK (TheStreet) -- TheStreet's Jim Cramer answers viewer questions from social media on the floor of the New York Stock Exchange.

On Tuesday, the Internet is buzzing with tech and housing stocks. Investors want to know if USG (USG) has bottomed out after an almost 13% drop in the last four weeks. The construction-materials company is not a favorite with Cramer.

"I don't care for USG," he said. "If you like housing just buy Home Depot (HD - Get Report) ."

Whirlpool (WHR - Get Report) , Cramer noted, is taking a hard hit from its Brazil exposure, despite strong housing sales in the U.S. Analysts have reconsidered their estimates in light of currency headwinds and the weak Brazilian performance coming up to earnings.

Another hot topic on the stock exchange floor was Facebook (FB - Get Report) . Should investors hold or take their profits?

"If I were a trader at my old hedge fund, which I am not, I would be selling some to buy it back," said Cramer. "We don't do that for Action Alerts PLUS, though, we just own it," he added.

The social network is angling to take a bigger bite of its users' digital interaction, testing a shopping feature for in-app retail. The move would allow Facebook's news feed to double as a storefront.

As for less-established tech names like Zillow (Z - Get Report) , Cramer was not so  enthusiastic.

"What's up with Zillow? It's been all over the map," he said. The stock jumped 13% in September, reaching 52-week highs on Monday, but has seen large outflows of capital in October.

"It's just too hard for me," he said. "That includes Zillow and includes Yelp (YELP - Get Report) and it even includes Home Away (AWAY) . They've all just become too difficult to discern the direction."
