I think you are misclassifying Wikipedia when you call it social media.

I'm hoping that these statistics aren't per day, but the article doesn't specify.

Very interesting post. Finally one that focuses not only on statistics related to the US!
I am looking forward for more:)

Excellent !

great read!

This is not global at all.

f I had my own company, I prohibit my employees from accesing facebook during working hours

I really will someday understand why brazil still on the top of the penetration on social usage.

Why would Canada be omitted. At one point in time (not sure if it's still holds), we were the highest per capita Facebook users in the world

Excellent! Thanks for sharing!

It is per month

Where is Canada, that's a fairly large omission!

Hamish – I think crowdsourcing like Wikipedia would qualify as social media?

I disagree. Wikipedia is an information sharing medium developed, updated, and maintained by its users. It's an astonishing collection of information, larger than we've ever had or been able to create as a global community. Wikipedia, for all intents and purposes, is the gold standard in online collaborative behavior.

I think that are per month.

The average visitor spends 66% more time on these sites than a year ago, almost 6 hours in April 2010 versus 3 hours, 31 minutes last year.

Has Social Media Critical Mass with only 22% usage to change the marketing rules?

To say that any social event has the power to change the economy rules or market rules would have a Critical Mass. But I don`t know if the social media momentum has significantly big and extended through the society that self sustain and develop the capacity for changing how we do business…

Anybody Knows?

Excuse my ignorance but how are these stats sourced/created?

The author makes that point abundantly clear.

Totally agree! As a South African blogger for an SEO company, the chances of finding this kind of data is usually impossible!

Agree with Richard, I'd like insights on the source of the information too.

It's interesting about the comment on Wikipedia classification and I agree it's a sterling example of online collaboration. As for mis-classification, I've seen blogs filtered out of social media tactics and to me, blogs are often the hub of most business social media participation. They're social through the way comments enable conversations as well as many other features that can be added through plug-ins.

Very interesting to see how high Australia ranks.

I agree with Hamish. It takes more than just the information sharing … there is not a welcoming social appeal that encourages virtual handshaking or more than the intended purpose of the WIKI.
