If you're on desktop, the top of the sidebar will have their username. If you hover over that, it'll give you some longer string (like tumblr.username.com or something, I'm not really sure what it says). Click on that and it will take you to their actual blog :)

Haven't used tumblr in ages, but finally registered again to read some stuff people have posted. However, tumblr only seem to want to open their pages in the tiny sidebar to the right, refusing to letting me simply read their page as a, you know, page.

Googling only told me to open their pages in new tabs, but that didn't help; it just opened a new page of my feed with their page open in that darn sidebar.

Any advice?

How do you simply view a blog?
