Given the following:
1) how much we (as a species) relly on google search (or alternatives) to do most of our usual jobs
2) the rate and aggresivity of advertsing that keeps creeping into our lives

I predict that in the following years self-curated and group maintained indexes of search results and popular technical pages will become more and more popular

Something like torrent trackers but specifically for StackOverflow/Reddit-like threads and questions
