+Standard Talk (20 min).
 
 ***** Abstract
 
-I have been a long time user of static site generators, such as
-Jekyll.
+Org-roam is a Roam replica built on top of the all-powerful Org-mode.
 
-I recently discovered Org Mode's publishing features and started
-appreciating flexibility and capabilities, especially when literate
-programming comes into play to generate "dynamic" content.
+Org-roam is a solution for effortless non-hierarchical note-taking
+with Org-mode.  With Org-roam, notes flow naturally, making
+note-taking fun and easy.  Org-roam should also work as a
+plug-and-play solution for anyone already using Org-mode for their
+personal wiki.
 
-In this talk/tutorial I will present the challenges I faced and how I
-finally moved my homepage and the University of Trento's Computational
-Logic website to Org Mode.
+Org-roam aims to implement the core features of Roam, leveraging the
+mature ecosystem around Org-mode where possible.  Eventually, we hope
+to further introduce features enabled by the Emacs ecosystem.
+
+# ----------------------------------------------------------------------
+
+The purpose of the talk is to present some technical aspects of
+Org-roam.  From the very beginning, we wanted Org-roam to scale with
+your notes, and this meant that we had to keep a close eye on our
+performances.  As we iterated, optimisation remained a top-priority,
+leading us to constantly peek under Org-mode's hood.  Not only has
+this made us better developers, but it has also uncovered paths of
+optimisation for Org-mode itself.
+
+The talk is targeted at software engineers willing to peek under
+Org-mode's hood.  A rudimentary understanding of Elisp will be
+required.
+
+Points to be covered
+- SQL database via emacsql
+- Elisp libraries
+- Parsing of Org-mode files
+- org-elements.e
+- Parsing with a background-process
+- Ensuring consistency via hooks

+***** Abstract
+
+Macros are a powerful tool.  In the context of Emacs Lisp programming
+they can also provide us with a "foot-gun" of immense proportions.
+Join the dungeon-mode project as we trip over our own macros, so to
+speak, in the context of building a GPLv3+ turn-based role-playing
+game engine and game design features for Emacs.
+
+In this 20m talk I'll briefly introduce some rationales leading to
+storing all game source and play state information within org-mode
+documents (spoiler: it's about freedom), then go into some detail
+around the "ETL" process design that currently accomplishes this.
+Finally, we'll look closely at one especially problematic macro deep
+within this solution, and invite people to throw fruit^11^dhelp draw
+conclusions, ask questions, and discuss.

-
-***** Abstract
-
-Macros are a powerful tool.  In the context of Emacs Lisp programming
-they can also provide us with a "foot-gun" of immense proportions.
-Join the dungeon-mode project as we trip over our own macros, so to
-speak, in the context of building a GPLv3+ turn-based role-playing
-game engine and game design features for Emacs.
-
-In this 20m talk I'll briefly introduce some rationales leading to
-storing all game source and play state information within org-mode
-documents (spoiler: it's about freedom), then go into some detail
-around the "ETL" process design that currently accomplishes this.
-Finally, we'll look closely at one especially problematic macro deep
-within this solution, and invite people to throw fruit^11^dhelp draw
-conclusions, ask questions, and discuss.

-***** Preferred format
-
-Standard Talk (20 min).
-
-***** Abstract
-
-Org-roam is a Roam replica built on top of the all-powerful Org-mode.
-
-Org-roam is a solution for effortless non-hierarchical note-taking
-with Org-mode.  With Org-roam, notes flow naturally, making
-note-taking fun and easy.  Org-roam should also work as a
-plug-and-play solution for anyone already using Org-mode for their
-personal wiki.
-
-Org-roam aims to implement the core features of Roam, leveraging the
-mature ecosystem around Org-mode where possible.  Eventually, we hope
-to further introduce features enabled by the Emacs ecosystem.
-
-# ----------------------------------------------------------------------
-
-The purpose of the talk is to present some technical aspects of
-Org-roam.  From the very beginning, we wanted Org-roam to scale with
-your notes, and this meant that we had to keep a close eye on our
-performances.  As we iterated, optimisation remained a top-priority,
-leading us to constantly peek under Org-mode's hood.  Not only has
-this made us better developers, but it has also uncovered paths of
-optimisation for Org-mode itself.
-
-The talk is targeted at software engineers willing to peek under
-Org-mode's hood.  A rudimentary understanding of Elisp will be
-required.
-
-Points to be covered
-- SQL database via emacsql
-- Elisp libraries
-- Parsing of Org-mode files
-- org-elements.e
-- Parsing with a background-process
-- Ensuring consistency via hooks
-
-***** (Un)availability
-
-I am in CET, and I would rather have the presentation early in the day
-(9am-12pm EST would be stellar).  If need be, I could present later,
-but I do not think I would be as effective.
