I work in embedded, web & app dev and for web or app dev, by far most customers really don't care what it is written in. They care about the end result only. So we can use whatever is the closest to the endresult already and that's not often something like Rails. More often than not it is actually Wordpress; someone in this thread mentions web projects are more often <100 hours than years (for embedded we think in years, web/apps in 1-3 months) that's why WP is working; our clients do not actually care about maintainability because it's a quick write and will be thrown away / replaced when it served it's purpose.
