TheStreet's Jim Cramer answers questions from Twitter on the Netflix/Comcast deal, Facebook's purchase of WhatsApp and its effect on Yelp's price, and Apple downgrades. Cramer says if Netflix can increase the reliability of its streaming it will add subscribers to the service. However, Cogent and other middlemen may be affected by the deal. Cramer also says Yelp is one of the "finest" companies and investors should have bought shares "a long time ago." Finally, Cramer says Apple's recent downgrades are based on its lack of revenue growth but he is willing to sacrifice short-term performance in return for future gains, which Apple can come up with.
