While I personally don't mind Google having all my backup data, we must appreciate the fact that in this post-Snowden world some people will justifiably refuse to go with the big USA-corp players like Amazon or Google.
rsync.net just saying: "Hey, we're not Google or Amazon" is already a big selling point for some.
I encourage you to email us and ask about the HN readers discount.
Further, Amazon S3 is a better comparison, as far as pricing goes - we're fully live, online, random access storage - not nearline or weirdline like google/glacier.
We have a "HN readers" discount which is fairly substantial.
