For real. I put together a simple Jekyll blog, and figuring out gems and this and that after not looking at Ruby for 15 years was a real slog. A lot of that was my fault for being out of the Ruby loop, and being unfamiliar with Jekyll, but I feel like the process could have gone a little more smoothly.

Anyway, this made me excited to try Ruby again.
