Having access to much less information made it easier to focus.
The abundance of information is great, but it's much, much harder to focus.
Also, of course, as information, especially technical, was mostly available through formal education, books and magazines, which were all expensive "businesses", the average quality of information was much higher. Publishing crap content was risky and thus relatively uncommon. Now that publishing content is virtually "free", obviously the average quality of availlable information has dramatically decreased. Now if you have enough background to sort it out, it's great. But if you don't - if you're still learning the basics - then it's a hellhole.
