MTB Blues

I've been riding a geared, full-suspension 26er mountain bike for three months now. It is not ridiculously heavy. It is not lightening fast. It has nine different gears, which are eight more than a singlespeed, and two fewer than the latest trick componentry. Its suspensions is around 140mm, which can handle most trail things but not, I imagine, massive hucking. It seems from my inexperienced view to be a competent but uninspiring machine.

Despite its stolid capabilities, I struggle to feel comfortable with it.

my mountain bike

My new bike has 26" wheels. A few die hards laugh and say a good rider can ride anything, but this logic is obviously flawed: Yes, the fittest rider in any group can ride the lowest-performing bike, but we can't all be the fittest rider: Most of us have to be clustered around the mean. That's science, folks. If I'm in pretty-much the same shape as everyone else, and if I'm working 3% harder than everyone els

Some people have told me that they WANT companies knowing their preferences to create a "better web / inter webs experience"

--Alan Armstrong

Typically, people assume that if companies have lots of information about them, the Internet will be pretty-much the same as it is today except the ads will all be for things they like. Win-win!

But that's not how it works. It's not just the ads that will change. Reality as you perceive it will change. When friends post complaints about products, you will see less of those complaints on Facebook and Twitter, and you'll see more positive reviews, because that's what encourages you to click on ads and buy things.

What they know about you will affect what you see on social media like Facebook or Twitter, what news stories will appear when you go to a "newspaper" like torontostar.com, and what products you will find when you do a search on Google, within Amazon, or on eBay.
