I'm a web developer. I've never written a hash table, heap or bubble sort. I just use tools provided by the platform. But I've found it helpful to understand the tools that I'm using, and can't really imagine any programmer who wouldn't, unless they've never connected the dots between the theoretical knowledge they obtained and the tools they use every day to do their job.

Well, I think you're taking the other poster too literally. They probably mean "I've used the knowledge I gained in my computer science degree, MINUS the knowledge the average developer who doesn't have a CS degree, maybe twice".
