There's a difference between big sites using a particular stack and people (thinking mainly pointy haired boss MBA types) having heard of it. Lots of people have heard of wordpress because they have probably visited blogs with URLs that look like something.wordpress.com and they may have used it to write their own blog. Some people will have heard of rails because it had huge hype at around ~2006 and very vocal advocates including 37s who were known through other avenues because of basecamp and because they blogged a lot. Django on the other hand you may well not have heard of unless you have some knowledge of python or MVC frameworks (or read HN).
