Gmail is hacked
I never thought that i could every write this, but according to this. it seems that it's wasn't that safe.
I'm holding my personal email on google, and i use google apps for this domain, and i'm totally depending on it and i guess everybody else does.
the problem was that if you was logged in to your gmail and you opened a webpage containing a certain code, this page could create a filter in your gmail to redirect some of your emails to another email address. simply check your filters to make sure you are safe.
lots of blogs describe exactly how this was made, to know more you can check about it here and here.
