Someone on @HAGOODMANAUTHOR's live stream last night (07/01/2018) asked about how to go about releasing/distributing a 700+ page analysis on Clinton's Unsecured Email Server, I believe, and so I have some thoughts & suggestions. This is just a quick rundown and isn't an exhaustive list so anyone that has other suggestions is free to chime in.:
H.A. mentioned Medium.com. I've not used their service before, but it looks like a viable option.
H.A. also mentioned Steemit.com (that's what you're reading this post on here). This is a block-chain blogging, social media site with it's own digital currency reward system that's very interesting. The more people commit to contributing & investing time to the steem block chain service, the more valuable the service becomes. Other sites like Busy.org and d.tube use the steem block chain as well.
Start a free blog on Wordpress.com or Wix.com. While their free blogging site features they offer are limited, they're very easy to use & allow for a bit of customization to make it personalized to how you want it. You can also upload your own files to share on the site such as documents, images, videos, etc. If your blog really takes off & becomes successful then you can upgrade it to their paid services to unlock more powerful features for your site. Alternatively, you can purchase & host your own domain from a site like GoDaddy.com then migrate your blog site from Wordpress.com to Wix.com to have a fully capable, self managed website that YOU own.
If you'd rather just keep things simple, stick to using Twitter, & not go through the trouble of starting & maintaining a blog then you can create a Dropbox.com account for if you don't have one already. There you can have up to 2GB free space to upload files you want, share them, & provide a link to people you want so they can access the content. Here's an example of a shared link I just did to my private Dropbox that explains how to use Dropbox in case you're unfamiliar.

Hope this helps!
