I have about 4 at the moment self-managed vps servers and a vps reseller account. The 4 self managed servers I have are running nginx+mysql for web hosting and I have no problem with wordpress or any of the static sites I have setup. They are the cheap plan 256MB RAM so nothing over powered. Requests are quicker then my shared hosting with hostgator which is amazing considering I pay more for that then I do all for of the self managed vps's. For the issues I've had such as not being able to reach a server they worked with me within 15 minutes of opening a ticket and got it up and running in about 45. Just a great company and I wish for them to be around for awhile
