Nope it sure isn't greed to make money off a product or service, but I've never seen any numbers even HINTING that they need more money in order to provide a functional, profitable, and quality service. The fact is you have provided no evidence that the margin is in fact 'quite slim' and thus extra bandwidth cannot be purchased or installed.

What percentage of an ISPs overall operating costs does bandwidth normally represent? With 2000 customers at $29.95 thats just shy of $60,000 monthly. Your "upstream port capacity" costs less than $9,000 per month currently. You forgot one key part of your post, the part which explains why the ISP cannot purchase more bandwidth in order to satisfy its customers.

The problem is always greed, not technical limitations.

I'm all for banning cars inside theaters, churches and restaurants...
(we're not talking about drive-ins)

What I'm getting at is your example is flawed. Mcgrew was not advocating banning pagers/cell phones everywhere, just in places where other people would be disturbed. I also doubt they would allow you to ride a horse into the movie theater, even if you bought an extra ticket.

It is worth noting that 500 million active accounts, does not equal 500 million active people. There are plenty of people with multiple accounts, and plenty of accounts created solely to spam others. Of course it might be the best measurement we have to determine its popularity, but we shouldn't consider each account as a unique person. The same problem occurs when looking at the number of IP addresses accessing Facebook, as many people use multiple devices (or access points) to visit Facebook.

The explosion happened last year actually, but Zuckerberg did not win person of the year in 2009. To to say "2010 was a huge year for social networking" is not inaccurate, however an equally valid statement would be "2010 was no bigger a year for social networking than 2009". If you look at the numbers announced by Facebook it Increased by 200 million users, between September 2009 and July 2010(10 months) the same growth rate between April of 2009 and September 2009.
Cite for my numbers: Facebook.com

Facebook (2010)
Continued growth at almost exactly the same rate as 2009
Facebook launched 'Places' (Foursquare-like service)
Facebook launched 'Questions' (Yahoo answers-like service)
'The social networking' was released to theatres

Wikileaks on the other hand released (in 2010):
The Collateral Murder video.
92,000 Afghanistan war files
400,000 Iraqi war files
251,000 US diplomatic cables

Now regardless of how you view Wikileaks, it would be foolish to say it has influenced events less than Facebook. One caused a United States citizen and military private to be put into solitary confinement for 7 months, without trial (or a pillow), the other produced their own version of existing internet services.

Would this be due to the limited types of plastic which can be used with a reprap, or for some other reason such as the inaccuracy of the machine? I would love to know more about the limitations of these repraps and other CNC machines unfortunately that is beyond the scope of TFA.

yes but he said $300m, at $15 per plex thats roughly 20m plex. The key is he said dollars not kronas.
