Ok, so IPFS isn't for hosting and it's not for unpopular content.

What is it for then? For scaling distribution, you say. What problem does it solve? How, what and why? Is it better than BitTorrent for that use case?

it's better than bittorrent because you don't need a centralized tracker.

That's not much of a benefit, as there are tracker less torrents.

Also content can be incrementally updated without duplication.

Ok, when or why would you use IPFS instead of something else?

lol, you can troll better than that, c'mon :)

Are you just unable to answer the question or are you just so new to the interwebz that you think that was a troll?

ZFS is less flexible in deduplication because it's not true content addressing, and git has lousier protocol. Rsync and unison also have lousier protocol and don't deduplicate storage.
