Finish content for blog posts (mostly)

@fardog @ngoldman @pdxmele, @vosechu helped me figure out what was wrong with the blog posts from yesterday. These are fixed - though still a bit messy on the home page. I will send a separate PR with a few teeny tiny styling changes to give them some breathing room. :)

* I wrote the blog posts quickly so there may be typos or further edits needed - please feel free to just jump in and change them!
