Reasons for and against using paid themes.So, let's talk about paid themes, and when you should and shouldn't use them. Let me put it this way, you don't always have to use a paid theme if you're using Wordpress. People say that that's another thing you need to be taken seriously, but I think they're wrong. I've seen plenty of blogs on free themes, and I take them just as seriously. You should probably use a paid theme if you're looking to start a blog network, or become an authority in a niche, and/or somehow become widely known from your blog. Also, if you're looking to build a static site on WP, there are paid themes/plugins that will accomplish this, (there may be some free ones, but as of now I'm not aware of any.) You should use a free theme if you're starting and/or maintaining a personal blog, just starting out with blogging in general, and/or are just doing it for fun. You can also start out with a free theme if that isn't in your budget right away, and redesign 6 months later. Some blog hosts also have Paid themes, Tumblr is the one that comes to mind. ThemeForest has themes for Blogger as well.
