the tech-blogs' perception of google is so far off reality. google isn't loosing. google just entered a new market (social) which has a huge barrier of entry, thus they're fighting to get a foot in this door. within their traditional domain (search/advertising) they're unrivaled.
all the "google is doomed" talk is based on the potential entry of facebook into the search market. however, this hasn't happened yet and if or whenever it should we'll see how that goes. until then, i'd like to not read the same shit over and over every day on hackernews.
