I recently got into blacksmithing, and having scoured the internet for good tutorials I found there wasn't really a good repository of high-quality tutorials. So I made one.
I wasn't looking to do anything super impressive development-wise with this, but more focused on execution and useability.
Another Wordpress based site, I got very positive feedback from my Reddit post about it and get an average of 300 or so views a month.
Turn around time on this was about 20 - 30 hours, including content.
