There are many themes out there littery thousands of them, which is the best one? Well there are many to chose from paid themes or free themes. I have done plenty of research and have found the paid themes are the best ones why? Because they offer much more versatility you can do more to them than a free theme, don’t get me wrong there are plenty of free good themes out there but I find them limited to how you can manipulate them.
WordPress has some nice free themes like the twenty eleven, twenty twelve and so on, themefrost is another good site for themes there are plenty to chose from. I like the studiopress themes that run a genesis framework. Framework is the Motor that runs the theme pretty much you can have the best looking theme out there but under all the paint and glimmer is the motor that runs it any good or limited to what you can do? Genises is a bullet proof SEO ready one of th best around I have found, obviously the genises does cost you to buy it. Worth every cent the genises framework I run them on all me sites that I have.
