Punctuate marketing headings with a period. Fix a couple of
title-cased headings to sentense case. Consistently use curly
apostrophes, curly quotation marks, and Unicode ellipses.

Arguably this is one we should save, since it is a distinctive feature not
offered by all of our competitors, and it gets some additional visibility by
being in the left sidebar. The model of having multiple things in the
sidebar pointing to the same article is getting messy though, and as our
feature count increases the cost of having stuff in the left sidebar is
increasing as well.
We got asked about this from a potential user, and they seemed fairly
excited and confused by it. In particular, it wasn't obvious that
deactivating a user was the feature they were looking for.
Ideally these shouldn't have spaces around them either, but the
font we're using (at least in my browser) has em-dashes that
hardly merit the name -- about twice the width of an interword space.
So I leave them bulked up with spaces.
This isn't very slick, but it should get the main points down,
and it's past time we got something like this up. Definitely
needs in the future another pass at the text, and also some images
(screenshots, etc.) and styling.
