"don´t make me think" by steve krug (is a classic)

if you wanna learn about users, the way they think, and which problems they have on the web (eg with forms,..) just sit by your girlfriend, your mum or everybody you can watch in front of a computer.

the best is to watch them using something you created. so you get a clue of how different problems (than you think) other people have that you might think.

i was yesterday at a customer showing my progress. so he (a trainer for wordpress stuff) registered on the site and asked and did some (for me) weird things.

there´s tons of things to learn from that. :)
