Often the answer to the question was simply wrong, as it answered a different question that nobody made. A lot of times you had to follow a maze of links to related questions, that may have an answer or may lead to a different one. The languages that it was most useful (due to bad ecosystem documentation) evolved in a rate way faster than SO could update their answers, so most of the answers on those were outdated...

There were more problems. And that's from the point of view of somebody coming from Google to find questions that already existed. Interacting there was another entire can of worms.
