I've got shit to do ...
I could answer, I got to know lots of interesting people. But that would happened in the real world, en passant. I could mention the skills I acquired, commercial aptitude and geek-status ... but who cares. I always stress the relevance of both grassroots and traditional media content joining rows in the virtual domain of the net, but except for advanced search features (of which I'm still not sure wether they cost me my fluency skimming over a text) it would just mean more trips to the library - as for now, I stll have to learn not to purchase all the books I could ever want to read or cite ... The other point is communication, but emails are just a tad faster than letters: I hear penpals manage similar content throughput in both media.
No, the only constant enrichment directly related to my contact with internet technologies is entirely (if not excessively) non-technical, non-communicative and only good for a few hours a month: it was probably amazon.com that offered 30s-mp3-clips of Little Plastic Castle and other songs, which I subsequently ordered ... and later I purchased more from Righteous Babe Records. Her songs, sometimes funny, sometimes melancholic, always witty, still make me laugh and cry and think after almost ten years.
