What they fucked up: Read mores.

How they fucked it up: When people add a read more to a post, tumblr is replacing it with a line break, and all the content under the read more line is still right there on the dashboard, leaving it clogged up with gif hunts and other long posts.

How to get around it: Save the post as a draft, without the read more break. Then, go into your draft, select ‘Edit’ on the post, and insert the read more. Save the draft again just to make sure the read more break stayed, then, publish the post from your Drafts folder.
