Ever notice that sometimes you can buy a new printer for less than that replacement ink cartridge for it? The printer manufacturers went to the Gillette School of Marketing—give the printer (razor) away, the real profits are in the ink (razor blades). Take a look at this graph, HP Ink is more expensive than oil or blood!

Worse, most of the cartridges that come with printers are what the industry calls “light loads,” they don’t have a full amount of ink or toner you get with a new cartridge.

When I got my MBA, for one class I was part of a virtual team of 5. One member was in Bosnia, one in Singapore, and three of us scattered across the US. Every week we wrote a paper using Microsoft Word’s track changes feature and email. That was my first truly global collaboration, but there weren’t great tools readily available.

Did you know that United Airlines has a “flat tire rule” that says if you miss your flight (within 4 hours) they will rebook you on the next available flight?

Or that there was a double elite qualifying miles promotion from April through June?

One of the powers of Web 2.0 communities is the shared knowledge you can get.

If you fly more than once or twice a year on the same airline, head over to FlyerTalk (http://www.flyertalk.com).

I have been helping a friend with a website that is exploding in popularity, was developed in HTML/CSS and has no intention of switching to a CMS, and has a registration/supporters page that has grown too fast to maintain with copy and paste.

I did a quick Excel formula that generated equivalent HTML to what GoLive produced and switched the registration form to a Google form that leaves the results in a Google Apps spreadsheet (eliminating data entry).
