Starting today, you'll see things like promotional GIFs for Denny's in your web Tumblr feed (just like you had before via mobile), according to the company's staff blog. "These posts will simply blend in with the posts from the blogs you follow," says Tumblr, except that advert posts will be stamped with a dollar sign with lines shooting out of it.
Looks like Tumblr actually does sorta care about making money: mobile users will see "up to four ads per day, and they'll be differentiated with a dollar-sign icon with beams shooting out of it," reports AdAge. Subtle! Sadly, this revenue will be too late to save the editorial team Tumblr just canned.
