Provide an RSS feed on the Keybase Blog

At the moment, there is no official way to subscribe to Keybase news.

https://keybase.io/blog while beautifully simple has no RSS feed for use in syndicated readers, and even https://twitter.com/KeybaseIO makes it known that it's not yet an official account.

As Keybase grows, being able to subscribe to news is crucial, especially in the security realm.

For example, a few months ago, Keybase CLI asked me to make new keys. I panicked and uninstalled it. Today, I saw https://keybase.io/blog/keybase-new-key-model by near accident and now know what that was all about.

We need a way to subscribe to your news so that we know what's happening the moment it happens. Security is a serious enough subject to warrant that. At the moment, our only option is to follow an unofficial Twitter account and hope it doesn't lead us astray or become abandoned.

Claiming the Twitter account as official is certainly one solution, but providing an RSS feed for the official blog would be much better. If you can't provide an RSS feed with what you're using now, might I suggest https://wordpress.org/ ?

Start by inspecting the current implementation of https://keybase.io/blog and how its posts are published. Determine where an official RSS feed can be exposed and verify it represents the blog's news for syndicated readers. Done means readers can subscribe to a working feed for official Keybase blog updates.
