I feel exactly the same way. My brother is ten years older than me, so I discovered the Internet at a very young age. It was like a science fiction western, filled to the brim with hackers and webmasters.
Once I grew up and became a developer, I never found a community like the ones I saw when I was a kid. To me, even open-source projects often look like corporate projects in comparison. There was a sense of excitement back then that no longer exists today - or at least, I can't seem to find it.
I am filled with nostalgia whenever I see retro art, like the first edition of Shadowrun books.
