This looks great, I've wanted something like this for a while. Finding how to click through to the actual item in the feed was a high point of friction for me.

I went to a topic and then clicked on the header of something I was interested in expecting to be brought to the blog post directly. Needing to click on that same title again to be brought to the post was unintuitive to me, I searched around the page, went back and forth a few times and eventually figured it out.

As a user I would love to be able to click directly through to the article FROM the topic feed. I would expect that the comments is a URL to the page that the header currently brings me to. This would match my expectations from using sites like reddit/HN.

A one or two liner summary directly on the topics feed would be really great I think.
