Talk back to me!
Tumblr blogs like this aren’t really meant to support comments. They’re meant more for simplicity. I think of Tumblr as somewhere between Twitter and a more feature-rich blogging platform like WordPress.
I want to go one more notch away from Twitter, so I’ve installed Disqus (prounounced like “discuss” I assume) commenting. Each post will have a link to the Disqus comment thread.
When you comment, leave the radio button on “Unclaimed” and fill in the other fields. Easy peasy!
