Most VPS services must be fully managed by the customer. Improperly managed servers can lead to instability and/or security vulnerabilities. The hidden costs in time and effort can be a hindrance. I was spending more time patching and tweaking my rather pricey Linode instance than I was developing. Managed VPS services are great if you can afford them; I couldn't, and I knew I didn't want to go back to crappy shared hosting, so I started looking for an alternative.
I've been very pleased with WebFaction. It is shared hosting done right. All accounts have guaranteed RAM (shared processes like nginx instances don't count against the soft limit) and Linux cgroups to protect each account from other accounts' CPU and disk IO usage. They don't overload their servers either. You get most of the performance and maintenance benefits of a managed VPS, at the cost of traditional hosting ($9.50/month). Their documentation is good, support is responsive, and software is always up-to-date, so you can stay on the cutting edge. Whatever they don't have, you could always compile/install in your home folder.
