I've actually been deterred from Heroku because of the pricing. I find $7/month too much for a website or a blog, especially as I like starting new projects. There may be months where nobody visits my sites. I pay 2.49 euros/month for a VPS in Germany with 20 TB of free monthly bandwidth, 2GB RAM, 20 GB of disk space, no brainer. It's just a bit more manual.
