Most of the bad press Wikipedia has received has been on account of the negative perception of its ‘freely sourced’ content, and the fact that anybody can add or edit articles, with only the most basic monitoring of uploaded content in operation. Editing poor content on Wikipedia is largely the job of its large online community, many members of which spend their days trawling its content to find errors, and correcting them. The bias of some articles has led to some negative media coverage and criticism of Wikipedia, with some claiming the structure of Wikipedia allows some subjects to be biased to the extent of being inaccurate, or not accurately or comprehensively sourcing information and images. In light of this, many colleges and universities have banned the use of Wikipedia in any academic function except casual reading.

Freedom of Knowledge

Nonetheless, Wikipedia generally has good press at is is seen as being part of a movement to ‘democratize’ information, making it free and available to all. Wikipedia recently came out in ardent opposition to recent American anti – piracy laws, and effected a ‘blackout’ of its English pages for a 24 hour period. Many came out in support of Wikipedia’s ‘blackout’ strategy. Wikipedia’s growth over the years can be best shown in the form of statistics and graphs:

Current article count (English): 3,860,798+
Estimated number of words (English): 2,100,000,000+

This graph shows the general increase in the number of articles on the English Wikipedia over the years 2001 – ’12.

This is a visual representation of Wikipedia’s size, if its english articles were compiled into a physical collection. The size of this collection would, by now, be far too big for anybody to read in a lifetime.

Number of emails sent per day in 2009 : 247 billion
Number of emails sent per day in 2010 : 294 billion

So how many emails will get sent on a daily basis in 2011? While there are no confirmed reports on this as yet, according to the Radicati group, the number of worldwide email accounts will increase from 3.146 billion in 2011 to 4.087 billion in 2015. Roughly one-fourth of this is expected to be corporate accounts. And these corporate users alone are expected to send 33 emails per day (per user). This average number is expected to rise to 41 emails by 2015.

But 10 million is still a large enough number to make a general picture of what the social network now looks like. Thanks to work from FindPeopleOnPlus, here find the most important data about the demographics of Google Plus.

First, view the Gender Distribution on Google+

1. California : 159,841 (17.00%)
2. Texas : 119,906 (12.75%)
3. Florida : 108,963 (11.59%)
4. New York : 101,642 (10.81%)
5. Ohio : 75,768 (8.05%)
6. Pennsylvania : 73,420 (7.81%)
7. Illinois : 72,306 (7.69%)
8. Michigan : 68,683 (7.30%)
9. Georgia : 57,398 (6.20%)
10. North Carolina : 56,895 (6.05%)

Here are some more highlights from the study:

• The states of California, Texas, Florida, and New York together account for roughly 30% of all US game players.
• The highest ratio of game players to state population comes from the State of Wyoming
• The highest ratio of game players to city population comes from St. Louis, Orlando, Salt Lake City, Dayton, and Pompano Beach
• Despite a population of almost 650,000 – the city of Boston only brought in 1,792 gamers

Total number of people using the internet : 1.9 billion
42% of these users are from Asia
Total volume of data on the internet today : 5 million terabytes
Data volume indexed by Google : 200 terabytes (0.004%)
Total number of domain registrations : 193 million
46% of these domains are .com

Where does all this unindexed Google data lie? My assumption is that a good chunk of them must be secured information – email, document attachments,etc. But again, these alone cannot be 99.994% of the internet. What are your thoughts?

But the ground reality is pretty different. Gmail is not the biggest email service provider yet. It never was. A post here on Tech Crunchies last year put Gmail at number 5 in the American market. How are things now? Here are the numbers

1. Yahoo Mail : 72.8 million
2. Hotmail : 48.5 million
3. Gmail : 25.1 million
4. Inbox.com : 7.4 million
5. Me.com : 3.1 million
6. Outlook.com : 1.9 million

Interestingly, the study does not include MySpace and AOL Mail in the list. Ironically, these two services were at number 2 & 4 respectively in the list made last year. Wonder what happened to them!

So what does this mean to social network access from mobile phones. As a status update tool, Facebook today finds more usage among the mobile phone population than Twitter. That, along with the fact that Facebook enjoys a user base of over 500 million, has meant that Facebook is used by close to twice the number of mobile phone users as Twitter. Here is the % of mobile phone users accessing the various popular social networks

Facebook : 52%
Twitter : 24%
FourSquare : 5%
MySpace : 2%

Here are the top 10 countries ranked on the basis of the average number of hours spent per visitor per month.

1. Russia : 9.8
2. Israel : 9.2
3. Turkey : 7.6
4. UK : 7.3
5. Philippines : 6.2
6. Canada : 5.8
7. Indonesia : 5.3
8. Finland : 5.0
9. Spain : 5.0
10. Puerto Rico : 4.9

Worldwide : 4.5

A recent study by Pew has summarized the user demographics of services like FourSquare and Gowalla that you can find below. All numbers are as percentage of internet users in the United States

Male : 6%
Female : 3%

Race

Black : 5%
Hispanic : 10%

Age

30-49 : 4%
50-64 : 2%
65+ : 1%

Annual Household Income
< $30,000 : 3%
$30,000 – $49,999 : 6%
$50,000-$74,999 : 6%
$75,000+ : 4%

Education
Less than High School : 5%
High School : 3%

Here are the various online marketing channels and their popularity in terms of the percentage marketers who used it.

Email Marketing : 97%
Company website : 96%
Social media marketing : 82%
Search Engine Optimization : 79%
Search Engine Marketing : 72%
Mobile Markating : 22%

Does it surprise anyone that companies do not seem to be using SEO as much as one may have imagined? Or is it that SEO has become too expensive and unreliable compared to Social media marketing?
