Whilst I enjoy reading and learning about dapps, blockchains, etc. they seem very niche at this point: it can be argued whether or not bitcoin is "mainstream" (many have heard of it, but how many have or use it, compared to e.g. bank accounts), but ethereum is even more niche in comparison; using dapps is presumably rather niche even in the ethereum world, compared to those simply speculating on ether or making pump-and-dump ICOs; those building dapps would be even more niche; those building dapps with IPFS for distributed file storage would be a niche part of that.
I don't think this is what's driving IPFS.
However, I do come across many potential uses of IPFS every day.
Whenever I see a broken link, especially for some old informational site or tarball or whatever, and Googling for an alternative link just brings up more and more of the same broken link, it makes me wish IPFS were around (most recent example: http://easyldap.exofire.net/files/installer/easyldap-install... )
Likewise, whenever I find myself writing a URL into a file, e.g. a source tarball for a Linux package, I want to use an IPFS hash instead (IPFS is hopefully coming to Nix at some point https://github.com/NixOS/nix/issues/859 ).
In the latter case, I could add these files to IPFS myself, but I'd probably be the only one using it, and I'm usually less reliable than those canonical HTTP URLs, so those hashes would likely disappear sooner than the HTTP ones.
I have high hopes for IPFS. At one point I thought magnet URLs might solve this. I was pleased when kio-magnet allowed KDE to browse Web sites via magnet links, but even the blog post announcing that seems to be no more :( https://www.reddit.com/r/linux/comments/ew0y4/kiomagnet_what...
