As a geek I always hitting some tool that I say "If I know about it before!!!"
or some news in a blog entry that I say "How he/she hear about it"
or some article of "How I missed that"
or some anything on the web that I may say "It seems that I'm the only one who doesn't know about it"
So as a geek
what is your greatest way to discover new things
to avoid being behind-the-date
