Probably a bit OT. ... bare with me ;)
For me the "... achieve our goals" is the important part here. ... Users want to "get work done". Most of them really don't care about the underlaying technology. ... They know files, they know e-mail and some of them know dropbox. That's it.
Many users go a really long way to keep their data "file based", but still need / want a platform to share it with their community, in a relatively easy way and "privately" if needed.
IMO this behavior isn't economically useful, but that doesn't matter. ... It's the status quo and changing it is really hard. ...
I do like
this dat-intro by Karissa McKelvey very much. It sums up the reasons, why the dat-protocol was developed in the first place. (It's from October 2016. So I hope the goals are still the same.)
dat, imo has a slightly different characteristic than IPFS. While IPFS wants to change "the web" as a whole, dat uses a more conservative approach.
There is still the problem, to create an "incentive" for "players", that is good enough, to host user data. IPFS seems to bet on "filecoins", based on "eutherium". Which seems to be a possible business model. How it works out, will need to be seen. ...
For the dat-protocol I don't see many incentives at the moment. Except as "just an other file hosting service". Which isn't unique at all.
The beaker browser is a "different" beast. ... Is it the "killer app" that can push itself and the underlaying tech to get a critical mass? We'll see. .
Just some thoughts.
have fun!
