Just mine, yeah. Obviously, I want to avoid anything that's copywritten (the MCP6561 may be questionably fair use?) or proprietary (i.e., that I wrote in the course of a project). Also, publicly available models aren't interesting (you all know how to search manufacturers' websites, right?..).
Suppose I can add links to other sites. Could host others' files, just put them in a section, with a relevant description (including licensing, presumably something open?).
I want to add detail to a few; it feels like the S/PMETERs deserve an example. That would be an Altium project demonstrating them: PrjPcb, SchDoc, SchLib and ckt in a ZIP. I think I want more example material on my site, and little play/test circuits are an easier way to go about that.
