Tumblr overhauled its reblogging feature to add new options for interacting with chained posts, and it has not gone down well with many of the platform's users. The update, announced on Monday, represents one of the most significant structural changes to the service in years, and the reaction suggests the company may have misjudged how central this feature is to Tumblr's identity.
The update enables users to like, reblog, and reply to any post nestled within a reblog chain, with subsequent reblogs having their own note counts instead of a single aggregated figure for every version of the post. Previously, all interactions with posts in a chain flowed to the original author. The change breaks up what Tumblr calls its iconic collapsed reblog chain UI, something long considered to be a part of the platform's core user experience.
The new experience looks closer at how reblogs behave on X, Bluesky, and Threads, and the similarities have not gone unnoticed by many Tumblr users who are now pushing back against the platform becoming another Twitter look-alike. Users have flagged a practical concern: creators will not be notified of any comments, likes, and shares on the reblogged versions of their posts. This threatens the core dynamic of how creators gain visibility on Tumblr, where reach depends heavily on others amplifying their work.
The backlash has been swift and voluminous. With more than 35,000 overwhelmingly negative comments on the Tumblr announcement, users have made their strong feelings known. One user on X characterised the change starkly: "I have been on Tumblr for 16 years and this may be the worst change you have ever introduced." Content creators expressed particular concern. Some noted that a core part of the user base is made up of creatives, and this update will seriously hurt their reach while increasing the likelihood of harassment and making it harder to block the instigators.
Tumblr's defence of the change centres on attribution and recognition. The company wants to keep encouraging conversations and give contributors the recognition they deserve, allowing each reblog to have its own counts instead of one aggregated number from every version of the post. In theory, this could encourage more engagement at every level of a reblog chain. But the usability concerns suggest the execution has undermined that intent.
Tumblr acknowledged the backlash but still plans to roll out the update, saying that user reactions will be monitored as this rolls out over the next few days and users explore it. The company's willingness to proceed despite overwhelming criticism reflects a strategic choice: prioritising structural uniformity with competitor platforms over fidelity to what made Tumblr distinctive. Whether users will adapt or migrate elsewhere remains to be seen. For a platform built on its unique culture and mechanics, that is a genuine risk.
