Jim Cramer answers viewers' questions sent to #CramerQ on Twitter every Monday at New York Stock Exchange. This week he was asked if Salesforce.com is still a buy, and Cramer says he believes it is one of the best cloud companies. He was also asked about Starbucks and whether a slowing China would hurt the company. One Twitter follower asked about the Alibaba IPO and wanted to know if it would impact other internet stocks. Cramer thinks there is another Chinese internet company worth looking at.
