-## 6.1 publishing and blogging
-### 6.1.1 blogging
-Blogging is pretty straightforward since it generally just involves publishing lightly-formatted text,
-interspersed with media such as images and videos or perhaps social media posts.
-Markdown is a great tool for this job, and has been integrated into the system to much success:
-There are two different types registered with *converts*: `text/markdown` and `text/markdown+span`.
-They both render to HTML (and DOM nodes), so they are immediately viewable as part of the system.
-The only difference for `text/markdown+span` is that it is limited to a single line,
-and doesn't render as a paragraph but rather just a line of text.
-This makes it suitable for denoting formatted-text titles and other small strings of text. 
-
-The problem of embedding other content together with text comfortably is also solved easily
-because Markdown allows embedding arbitrary HTML in the document.
-This made it possible to define a set of pseudo-HTML elements in the Markdown-convert,
-`<mmm-embed>` and `<mmm-link>`, which respectively embed and link to other content native to mmmfs.
-
-### 6.1.2&emsp;academic publishing
-<div class="sidenote" style="margin-top: 1.25rem">
-One of the 'standard' solutions, <a href="https://www.latex-project.org/">LaTeX</a>,
-is arguably at least as complex as the mmm system proposed here, but has a much narrower scope,
-since it does not support interaction.
-</div>
-
-Academic publishing is notoriously complex, involving not only the transclusion of diagrams
-and other media but generally requiring precise and consistent control over formatting and layout.
-Some of these complexities are tedious to manage but present good opportunities for programmatic
-systems and media to do work for the writer.
-
-One such topic is the topic of references.
-References appear in various formats at multiple positions in an academic document;
-usually, they are referenced via a reduced visual form within the text of the document
-and then shown again with full details at the end of the document.
-
-For the sake of this thesis, referencing has been implemented using a subset of the popular
-BibTeX format for describing citations. Converts have been implemented for the `text/bibtex`
-type to convert to a full reference format (to `mmm/dom`) and to an inline side-note reference
-(`mmm/dom+link`) that can be transcluded using the `<mmm-link>` pseudo-tag.
-
-For convenience, a convert from the `URL -> cite/acm` type has been provided to `URL -> text/bibtex`,
-which generates links to the ACM Digital Library<mmm-embed path="../references/acm-dl" wrap="sidenote"></mmm-embed>
-API for accessing BibTeX citations for documents in the library. This means that it is enough to store the link to the
-ACM DL entry in mmmfs, and the reference will automatically be fetched, and therefore stay up to date with potential
-remote corrections.
-
-## 6.2&emsp;pinwall
-In many situations, and particularly for creative work, it is often useful to compile resources of
-different types for reference or inspiration and arrange them spatially so that they can be viewed
-at a glance or organized into different contexts, etc.
-Such a pinwall could serve for example to organize references to articles,
-to collect visual inspiration for a mood board, etc.
-
-As a collection, the Pinwall is primarily mapped to a Fileder in the system.
-Any content that is placed within can then be rendered by the Pinwall,
-which can constrain every piece of content to a rectangular piece on its canvas.
-This is possible through a simple script, e.g. of the type `text/moonscript -> fn -> mmm/dom`,
-which enumerates the list of children, wraps each in such a rectangular container
-and outputs the list of containers as DOM elements.
-
-The position and size of each panel are stored in an ad-hoc facet, encoded in the JSON data format:
-`pinwall_info: text/json`. Such a facet is set on each child and read whenever the script is called
-to render the children, plugging the values within the facet into the visual styling of the document.
-
-The script can also set event handlers that react to user input while the document is loaded,
-and allow the user to reposition and resize the individual pinwall items by clicking and dragging
-on the upper border or lower right-hand corner respectively.
-Whenever a change is made the event handler can then update the value in the `pinwall_info` facet,
-so that the updated position and size are stored for the next time the pinwall is opened.
-
-## 6.3&emsp;slideshow
-Another common use of digital documents is as aids in a verbal presentation.
-These often take the form of slideshows, for the creation of which a number of established applications exist.
-In simple terms, a slideshow is simply a linear series of screen-sized documents, that can be
-advanced (and rewound) one by one using keypresses.
-
-The implementation of this is rather straightforward as well.
-The slideshow as a whole becomes a fileder with a script that generates a designated viewport rectangle,
-as well as a control interface with keys for advancing the active slide.
-It also allows putting the browser into fullscreen mode to maximize screen space and remove  visual elements
-of the website that may distract from the presentation, and register an event handler for keyboard accelerators
-for moving through the presentation.
-
-Finally, the script simply embeds the first of its child-fileders into the viewport rectangle.
-Once the current slide is changed, the next embedded child is simply chosen.
