The issue, back in the days, you had to be part of "swapping" groups to get quick access to Amiga software (demos ...and ..warez).
In the beginning I did actually order some PD from 17 Bit, but eventually I got tons of stuff via friends aka swapping. Then you had BBS/modems.
Today there is no need for this. Pouet.net got most of what you need. There are also very active youtube channels posting the new productions (and old), like RetroDemoScene.
I guess you could add to that resevoir of preserving both old and new demos thru your website. The more, the merrier. I like to have software on my old harddrive, so adfs as suppliment to youtube/pouet is great.
