google is starting a sub site on everything ! which covers every niche...for example..they havehave an image site, video site, groups site, books site, products site, scholars site, a blogs site, and now reviews is integrated in their search, maps is there, they are now using gps to make every product/service they own to serve local communities, so do you think this will run majority of community sites down the drain? some will stay
Google will never be able to do that. People love change they will get tired of google everything and use google for what they need only. And go elsewhere for a change in crowd.
ya they will go to yahoo and from there to MSN and then back to google..... and we all webmasters will be either working for anyone of these 3 biggies or will be selling burgers at Mcdonalds
