Twitter just topped 465 million registered accounts. Facebook has over 850 million active users. Google+ has nearly 100 million. LinkedIn is over 130 million. Together, these networks are attracting vast amounts of time and interest from Internet users around the world, and those that participate on these services fit into the "content distributors" description above, meaning they're likely to help spread the word about your blog.

Nice sharing. Right these are the giant online social networks with huge amount of users. This can be good platform for increasing blog popularity over the glob.

The numbers which you have given for social networks is correct or not? but using these three networks we can drive huge amount of traffic.

Hi,
The way you have used the figures in the post is very impressive. I agreed with the point that, most of the time of internet users was consumed by these sites. Therefore, promoting the brand using such sites help to attract visitors to the website and increase the awareness of the brand among the internet users.

Really internet user could not ignore these and lots of people investing time on these websites.

I appreciate you for sharing such an knowledgeable and interesting post.
Thanks!
