I miss when TPB used to have a CSV of all their magnet links, their new UI is trash. I can't even find anything like the old days, pretty much TPB is a dying old relic.
So long as this distributed protocol has the concept of individual files, there _will_ be clients out there that allow the user to select `popular-site.archive.tar.gz` and not `less-popular.tar.gz` for download.
And what one person doesn't download... they can't seed back. Distributed stuff is really good for low cost, high scale distribution of in-demand content. It's _terrible_ for long term reliability/availability, though.
