This scares many Tumblr users who fear the same thing could happen to their preferred social network.
“If Yahoo! wants to be cool again it could just drop the exclamation point,” Tumblr user @jamiemottram wrote. Another Tumblr user, @nopelarry, warned: “bye never signing into tumblr again.” A third said “it’s been real good knowing you, Tumblr.”
“That was the old Yahoo,” Mr. Kagan said. “I wouldn’t say that would happen now. Yahoo is a different company now that Marissa is running the show. So it’s quite possible that this could be successful.”
