Hi,
Thanks a lot for the recommendations. Filtering by the blog tag is pretty useful, but doesn’t really solve the problem of how the theme looks. I did get to look at the themes I missed in the all themes list though, so that was helpful.
I don’t think requiring a textual description for every theme should be a hard requirement-mine is kind of an edge case, and most people can just look at the theme and judge that way. Maybe a “soft” requirement, if there’s such a thing?
Anyway, i’m off to look at the recommended themes 
Another thing I forgot to say in my previous post: thanks a lot for Hugo! i’ve been loving it (and the documentation, specifically) a lot.
P.S. I was looking at After Dark. Is this a good theme to get started with as well?
