Nevertheless, it's growing on us, too, like mold. We are just not very far into putting it in words and common familiarity and frames of reference. The user script is slowly shifting and reshaping our understanding of the web, into something it was not designed to be, but, as many of us have noticed, into a very powerful and shape shifting capabile organism. It's a paradigm shift I believe will evolve the web in a profound way, following along in the trail of previous paradigm shifts:
- The transition from the web as a set of loosely coupled static hypertext documents into server side dynamically generated pages
- The large-scale client adoption of XMLHttpRequest, shifting pre-AJAX-ian days to a part client side driven data flow
- The client driven orchestration or remixing of what the web page does, and how, by way of the user script. This is one of the presently evolving next steps, and useful patterns and practices are slowly forming around it.
But I'm losing track, here; let us get back to the podcast topics, again. A stigmergy structure is the result of emergent behaviour in a system, examples from the podcast being Wikipedia or the Linux source code, evolving over time from contributions by a large number of people, building something fit for a purpose that evolves around some small set of basic principles governing its growth. Or search engines, harnessing the web into a very large data mine, growing larger and more resourceful by the second.
Stigmergy is the method of communication in these systems: how one part sends a message to another part by modifying their common environment. Editing a wikipedia page, submitting a linux patch or writing a web page, registering it with the search engine or being picked up by it from external linkage. And it's a coming, very useful practice in user scripts too.
I recently dropped a reminder on my idea blog repository about finding or devising a gallery browser user script (and Instant Gallery is what came out of it), to transform any page with image links into a common gallery browsing application customized to my own liking, giving me the benefit of a user interface I like and could improve on incrementally and perfect, share with friends and the rest of the web, and use that, pan web, without any prior cooperation from web masters everywhere. This is the raw power of the user script.
Recognizing that we have a script that takes image links and makes a gallery from them, we can make a separate script that modifies a standards defiant web site into a standards compliant site with proper image links, prior to running the gallery script -- harvest the page for its image links, add them as proper links, and the gallery is set to go. No added to the gallery tool, easy plug-in fixes from other people who use other sites than I do, and want to use them with the script without to understand and modify my script or have my help doing it.
The web page, in a user script setting, is a stigmergic structure, where an ecology of user scripts can work together to build new and interesting applications, without the blessings of or participation from the webside page host.
And plain image links in a page, is a de facto micro format, specifying a gallery of images. The input fixup scripts can work their magic on a page for the benefit of any other script besides my (and Jos van den Oever's) gallery hack which takes that micro format and renders a gallery of it. We could just as well plug in another script that uploads a copy of those images to a Flickr account, stores them in Google Base or on some social bookmarks service, or anything else we might want to do with a bunch of images.
Making small scripts to bring structure to pages of some common traits and making other scripts to pick up on this structure and perform on it is a very useful pattern from biology that has lots merits in this computer science setting, too. Specialize, do your thing well, and share the result with other specialized entities who do theirs.
Next I would want to stigmergize-enable
GM_xmlhttpRequestcalls too, to provide the same ecology of specialized helpers to process page-external resources to the scripts I write that pull together data from many locations into tools like Book Burro. But let's play this one step at a time.
