I think there's another thing "different" now vs the 80s/90s: The decline of good computer magazines, and despite places like hn, the relative scarcity of good technical resources to replace them. No Byte, No Dr. Dobbs, and while there are still a couple of magazines dedicated to Linux, I find their quality versus the magazines for the Amiga is a bit uneven.

Personally I grew up reading Dr. Dobbs, Byte Magazine, a slew of Amiga journals and Scientific American. I probably started reading the latter at a point where I understood maybe 40% - but it was a great way to learn English.

On the plus side, you can now go and play with and read the code from the likes of Bernstein, Percival, Torvalds and things like the entire Solaris system. And there are great resources, like the Arch Linux wiki, the FreeBSD documentation and dev/user lists. But the good stuff is increasingly hard to discover in an ocean of mediocre stuff. And I have yet to find any good canonical resource for "the good stuff". One of my biggest disappointments with college was that academics appear to be doing a terrible job of keeping up to date, or helping students seek out good extracurricular resources, despite the fact that these resources keep growing and growing.

I hope that the trend toward open publishing of research will continue, and maybe see some sister-resources in the form of free popular science resources pop up -- I could easy imagine universities and research institution pooling resources in order to help researcher edit and publish popular science articles in addition to their standard papers -- as a combination of general science education, and to rise awareness/advertise research.
