I would love to switch to hosted ghost, but the pricing makes very little sense for a personal blog. An article will make the front page of hn or some larger subreddits and I'll get 30k views in just a few hours. I'd have to pay close to $200/mo to get the same number of page views I can get with a $10/VPS that I ssh into maybe once every 6 months to patch.
The pricing levels simply do not offer enough page views.
From the "unusually fair billing policy" section on the pricing page:
> Our plans are limited by how many readers you have, and how often they visit your publication. We only enforce these limits on a 3 month rolling average, so we'll never make you upgrade plans if you happen to have one big traffic spike or particularly successful month.
