Ghost is really cool. I funded the KickStarter campaign with high hopes. It’s perfect for a basic blog, but it in no way competes with the flexibility of WordPress. It doesn’t have custom post types. You can’t choose a page template or format. Apps are still in the works (no plugins), you are pretty much stuck with Disqus for comments, and we still haven’t seen a Dashboard. When it started I was sort of disappointed with just how lacking it was in features but really excited to see a new platform built around node. I was hoping the feature set would grow quickly and be comparable to key features within WordPress. This didn’t happen, so I’m switching back for now. I’m going to keep my eye on the project. It may surpass WordPress one day, but for now WP is my go to CMS.
