What is a spark?
Not a bookmark, note or a link – but a unit of interest.
A spark is something that caught your attention and might deserve more of it. You can choose - invest some time, curiosity and effort into this idea, or defer it for later. It could become a hobby, a project, a skill, or just something worth remembering.
Most of the saved content rots on the graveyard of good intentions because it requires effort to be resurfaced and used. Sparks are different. Easy to capture, find and act on.
Every capture becomes structured spark.md — insights extracted, connections made, context preserved.
