I wish there was some version of Wikipedia for people who speak good English (not Simple English), but aren't assumed to already be experts on the topic. Technical articles are pretty much impenetrable.
So you basically wish for Wikipedia to also feature simplified explanations of technical topics.
I don't think "good English vs simple english" plays into this.
It's not like the problem for technical articles being impenetratable on Wiki is that Wiki doesn't have an intermediate level between expert-talk and simple english.
It's just that it doesn't have simple english explanations of some technical topics.
