Tumblr is changing the way you use their website to share your thoughts.
Instead of having a separate compose page for posting new content, Tumblr now has the option right on the user’s tumblr itself.
This is similar to most social networking services like Twitter, Facebook and even Google+.
The new composer is aimed to show what the end post would look like. The company said:
Now you’re making posts the same way you’re reading them.
They are still in the process of rolling it out to everyone so you might not have it right now.
