Analytics
I want to know when my content is being read, and which content is the most valuable. At some point I want to add a way to "Continue the conversation", but for now I just want to track the activity on my website. I didn't use google analytics, even though that probably would have been the smart thing to do. So instead, I did the developer thing. I rolled my own.
Didn't take much, just a javascript component that pings my api with pageview information and a view to see that pageview information. I would be lying if I wasn't considering writing a blog article about my "roll-your-own" analytics component, but that's for another day, after the viewing of the analytics page isn't just a dump from the DB.
I'll probably use chartJS or something to make it look pretty, and when it's pretty that's when I'll share.
