Directories aren’t surging. There isn’t this nascent directory movement fomenting - ready to take on the world. Directories aren’t trending.
But there is a certainly really sweet little directory community now. From the Marijn-inspired stuff listed in Directory Uprising to the link-sharing ‘yesterweb’ collected around sadgrl.online - or the originals at Indieseek and i.webthings.
Barnsworthburning (by Nick Trombley) is a very formidable addition to this community - a clean, multilayered design and an innovative bidirectional index.
In order that the mind may not be taxed, moreover, by the manifold and confused reading of so many such things, and in order to prevent the escape of something valuable that we have read, heard, or discovered through the process of thinking itself, it will be found very useful to entrust to notebooks...those things which seem noteworthy and striking.
I'd like to call the more general phenomenon that this is a specific instance of "ghost knowledge": It is knowledge that is present somewhere in the epistemic community, and is perhaps readily accessible to some central member of that community, but it is not really written down anywhere and it's not clear how to access it. Roughly what makes something ghost knowledge is two things:
It is readily discoverable if you have trusted access to expert members of the community.
It is almost completely inaccessible if you are not.
In this sense, most knowledge is ghost, particularly if you take an expansive view of what counts as an epistemic community.
