When starting out, a shared host might seem like a bargain (“Unlimited page views!”). It comes at another cost: incredibly slow site speed and frequents down time during high traffic periods.
If you plan on publishing popular stuff, you’re killing yourself by running your WordPress site on shared hosting.
The stress of your site going down after getting a big feature is enough to create a few early gray hairs: don’t be a victim, invest in proper hosting.
My sites are always blazingly fast, never have downtime when I get huge features (like when I was featured on the Discovery Channel blog!), and the back-end is very easy to use.
Last but not least, support is top notch, which is a must when it comes to hosting. Take it from someone who’s learned that the hard way.
