+### [Event Chaining as a Decoupling Method in ECS][event-chaining]
+
+![graph: FileSignal -> AssetSignal -> AssetEvent](event-chain-assets-graph.png)
+
+[@jojolepro] released a [blog post][event-chaining] that provides
+an in-depth look at how using events in entity-component-system architectures
+can improve system reusability dramatically.
+
+Using events in this way also allows for:
+
+- easier testing,
+- additional configurability,
+- possible performance improvements,
+- higher usability - especially if using generics.
+
+The blog also has an [RSS feed][jojolepro-rss] and more in-depth posts about
+game development are planned.

+- Easily create ECS systems.
+- Create tiled and ASCII entities.
+- Create GUI elements.
+- Move entities around with A\* pathfinding.
