My first SDF account was created in 2004 (possibly before). In economic terms, the SDF services I enjoy with my sustaining membership have no equal. You'd be hard pressed to assemble the same portfolio of services from corporate providers-- ad-free, nag-free, no user productization-- for the same price.
But that's superficial. While I certainly enjoy the services that SDF provides, the community is what sets it apart. I've been here, and am still here, because of the community-- even if I've been quiet until recently. We're all a bunch of geeks of x, y, or z. Whenever I venture into com, I feel a sense of belonging. When I skim the local SDF fediverse feeds, I feel the same way.
SDF's banner offering is its community. Cheers, SDF!
On SDF, mostly. Locally, in a VM since a lot of my machine's bells and whistles are only enabled in Linux (and the commercial OSes).
