Facebook Like Button Still Most Likely Liked By Most Liked Sites

As per BridgeEdge Report ( http://www.brightedge.com/resfiles/brightedge-report-socialshare-2011-07.pdf ) Facebook is still leading the presence of its Like button among top 10000 sites than Google+ However Google+ is gaining rapidly 4.5% up. Given the fact that Google+ launched very recently it was a good future.

BTW another observation that only 49% site has either Facebook or Twitter button on the home page. So there is still a market for them to grow.
