For all the #nerds and #hackers among you - I highly recommend textfiles.com - a site containing thousands of files from the old times of BBS but some interesting things from the modern days as well.
For example try this - the Unix Haters Handbook - quite fun to read.

@dewb I so agree with that. Thank you @textfiles for setting up this genious web page - it is just amazing! Maybe you want to donate to Scott a bit :-)
