Well, that kind of shows the issue, right? I’m talking about what happened many years ago (nofollow links were added in 2005) - companies learned their lesson and wouldn’t try to pay expert writers and editors for reference-type content for web use anymore. Here is content that’s somewhat similar: encyclopedia.com.

By the way, I think Google and its easily-gamed algorithms that rewarded regurgitated content and mega-sites is more to “blame” here than Wikipedia itself for how it went down.
