I'm deeply skeptical of the overall value of the Internet even for those trying to use it for enrichment and not just entertainment/shopping. I'm sure some outliers manage super-powered learning with it, but I think for most it's more like a massive distraction of false work and wasted effort that occasionally yields bursts of high productivity, while being kind of crap on average compared with what could be done without it and without the distraction of an all-you-can-eat information buffet. Especially if you factor in the Skinner box nature of the modern Web and its ability (along with other hyper-available, giant-catalogue-at-your-fingertips entertainment, all also delivered over the 'net) to waste hours of time in seemingly the blink of an eye.
