Most folk who read this will know about xkcd – but if you don’t, I highly recommend you check it out. There is a pretty reasonable wikipedia article on it as well.
Today’s comic cracked me up..
Reading xkcd is not only humorous, it is educational. For example, the term Rickroll was brought to my attention a prior to the YouTube April Fool’s joke via xkcd – of course, this might simply serve as evidence of how uncool I am. More recently Hack a Day posted on a security concern with how ISPs are using failed DNS lookups to redirect people to advertising – to prove the point the security research rickroll’d users visiting the bogus links.
