Thanks to the Meta Team for their efforts regarding this!

I agree with some of the points brought up here. One thing is the description area is too small (and the other parts as well). I don't really notice also the read more button to expand the areas. Personally this is okay for the screenshots area and the rest, but perhaps making the description area bigger would fix this.

I also noticed that the search results are a bit awkward. Searching for "SEO" in both the new and current plugin directories give very different results. The old one showed SEO plugins, but Yoast SEO isn't on the front page. I don't know the stats on how many people are searching the keyword "SEO" but are actually looking for Yoast SEO, but I thought at least it would show up in the front page in the current directory.

But in the new one, searching for "SEO" showed Yoast SEO at the top. However the rest of the results have a lot of non-SEO plugins in the list (galleries, security plugins, social sharing, JetPack, and others). I don't think this is an intended result. And I think what happened is that a lot more weight was put into how established a plugin was and this has affected the search results.

I've commented on the Trac ticket about the search thing: https://meta.trac.wordpress.org/ticket/1692#comment:52
