Yes, but when it comes to suggestions about standard UI features, I’d be surprised if he disagreed. Apple sets a fairly clear precedent for how standard iOS UIs should work, and whether or not it’s in the Human Interface Guidelines, going against the standard Apple sets feels sloppy.

I would find it more likely that, even though (IIRC) the guy handling Instapaper’s support said he would pass it off to Marco, he simply didn’t see my suggestions or ever do anything with them.
