Obox copies Svbtle

It also includes some backend stuff that allows for customizations that Svbtle obviously does not.
So, while it is heavily derivative, and in some cases (the buttons) does rip off Svbtle, it's hardly a copy-paste bootleg. If it was, no one would buy it - the free wp-svbtle theme already does that.
Things that actually are problematic about the theme: - Change the buttons. Seriously. I don't even like the Svbtle buttons, with their absurd pill shape. This applies to the fields in the comment form as well. - Move the written-by tagline below the headline. It makes it much clearer what the tagline refers to, and allows the post header and site header to line up, which would look much better. I didn't like its placement in Svbtle, and I don't like it here. - The drop-down menus (another addition that doesn't come from Svbtle) look really odd because of the reversed color scheme, the space between the menu and the buttons, and the inconsistent border-radius between the top-level button and the drop-down menu.
In summary, Svbtle does not and should not have a monopoly on a two-column layout with a fixed left column and the basics of good typography implemented. Being minimalist is a style in and of itself, and this theme has significant differences. If it wasn't Hacker News' darling Svbtle, no one would be complaining - no one complains about the numerous WordPress themes based on Tumblr.
Maybe Dustin should have got a design patent. ;P
