Some of my teenager memories from the late 90s: suddenly finding communities sharing my niche interests (fantasy books, korg trinity sequences) that I never had access to. I also found Julius Smith's DSP book and several lecture notes from different universities which made a big impact on my career decades later. The only ads were for web rings, which seems quaint now. At least the DSP stuff was world class and freely shared.
