Today I joined a Quantified Self meetup at the Google Office here in Berlin. I have to say I don't like the direction this “movement” is taking.
I think what is missing is a common ground, an inspiring basis everyone likes, trusts and participates. Something like the Raspberry Pi, Wordpress, Wikipedia or Apache, – something you can build on.
The talks today were quite the opposite. Someone showed an application which is now free but will likely become crippled when the user base is large enough. Someone else plans a web site for blood tests per mail. Thank you, not for me.
