The main problem with corporate social software today is that the business dynamics are different than public social apps. With Facebook or Google+, you are a user, not a customer, and advertising is the business model. With corporations, you buy, not build the software and typically it is bloatware, trying to meet the needs of a selection committee with vague goals. So, if you can find anything good, it will be expensive (SAP, Microsoft, Oracle, etc).
Digital Equipment Corporation (DEC) had a vibrant social network from the mid-80's to the mid 90's, based on a rewrite of the CDC Plato software. It eventually evolved into Lotus Notes and bloated into crapware. In it's day at DEC, over 400 "notes files" were active, half business related - and non-business topics to encourage use by everyone. Below the management level, the company ran on "VAXnotes". Management hated it, because it wasn't the way they were comfortable working and disrupted their authority. Did this kill the company? Perhaps. It sharpened the disconnect between management and the workers.
Today, combine bloatware social tools that basically suck when compared to public sites, with corporate rules that discourage non-business use, combined with the spyware culture that social tool reporting provide - and we see failures due to non-use. Once those that grew up with social tools grow into management positions, the popularity of corporate social tools will likely grow. Use of social business tools "CAN" be a powerful tool if the corporate culture embraces it. It "WILL" make companies more competitive if the culture can act in a more coordinated way. Just, not yet.
My allergy to peanuts and cashews has been going strong for over 50 years and I'm still alive. Peanuts and cashews are the worst, and to me, the difference is like between a bee (peanut) and yellow-jacket (cashew) sting. Similar reaction, but stronger and nastier. Peas, lima beans and lentils also cause an allergic sensation, but won't get me sick
As a kid, today you get protected, but once out on your own, shit happens. In third grade, I knew I couldn't eat the peanut butter candy we were making in class, but wanted to help, so I stirred it. That got me sent home with my eyes swollen shut. Later in life, I've been hit by a "maple frosted" donut, learned about mole sauce and sate sauce the hard way (note to self; watch out if the E on the end of the sauce's name is pronounced as A). Those cut up garlic pieces in the dipping sauce at the Thai restaurant were actually chopped peanuts. Those rice crispy squares only had 1 tablespoon of peanut butter in the batch, but it got me. The chicken salad sandwich with cashews did too. I could probably die from a large dose, but sense it pretty quickly. What gets my goat is the warnings on packaged goods saying the product was made in a factory that uses peanuts. I ignore those labels and only sensed peanuts in M&M plains and a Hershey White Chocolate candy bar.
For me, the smallest bit ingested means I'm going to puke. It might take 10 minutes or three hours, but it is going to happen. Normally, once I know it is in my system (seconds after swallowing), I'll drink a bunch of water and try to puke it out of my system. That sort of works. I also get wheezy and my throat closes a bit, but not as bad as others report. Then, I get sleepy. Even the dust in the airplane gets my eyes itchy. Years ago, I tried the desensitization approach on my own, but didn't like the reaction and stopped pretty quick.
So in every area, they have a good estimate of how many cars have Bluetooth and have it turned on? For example, our household (HS senior, college sophomore, my wife and I) have 4 cars total and only one of them has Bluetooth. It is turned on. But, the rest of us have BT headsets - which are not in pairing / discoverable mode. So I guess they only "see" one of us on the road?
They don't need many samples to determine road speed conditions. On a busy highway, even if only 1% of the cars have bluetooth discovery enabled, there will be valid data. More valid as the sample size increases. Similar technology is used in airports to understand the speed of the people moving thorugh the security line.
If you think the system is working, ask someone who's waiting for a prompt.
