Ok it sounds geeky I know but since bit.ly have allowed a simple way to do this, lot of companies have stated a trend (pep.si, yhoo.it, 4sq.com, cs.pn) of having your own short URLS. So I got excited and created my own – http://mustafa.im/90UURD (ok not that short but it still makes me smile :).
Its very simple to do just sign up for a bit.ly pro account and hock up your own domain 🙂
