You're only going to become more intelligent if you take the time to read the content, articles and observations they share with their Twitter fans. Just hitting "Follow" isn't going to your IQ a jot.

How stuff works
An account that does what it says in the handle - How Stuff Works will tell you... we won't patronise you.
Some articles might require a basic understanding of engineering and science, others will take you through things from an 'idiot-proof' perspective.

Alain de Botton
Philosophy usually doesn't work on Twitter, reducing insights into horrible quotes that end up on Facebook statuses or on arty pictures. De Botton is an exception.
Quoting philosophical giants, his own words and his own work, de Botton offers up a smorgasbord of intellectual stimulus.
