Google to Launch Major New Social Network Called Circles, Possibly Today (Updated): "We believe that Google will preview a major new social service called Google Circles at South by Southwest Interactive today. Update: Google has now officially denied that Circles will launch here, but not that it exists. See final update below, as of afternoon Texas time Google does now deny that Circles exists. If what we've heard is correct, the service will offer photo, video and status message sharing. Everything users share on Circles will be shared only with the most appropriate circle of social contacts in their lives, not with all your contacts in bulk. Circles may be shown off at an event co-hosted tonight by the ACLU, an organization focused on privacy and the liberties it affords. It may not be a big public launch yet, but it's clear that this is a major product in the works at the very least. Please see below the fold for what I hope will be the final update on this for now."
