It can give benefits but all too often I'm left looking at a spinner wondering what the hell is going on before eventually being presented with a simple page that would have been trivial to render server side.
At first I said to myself, "C2, wtf is this guy talking about I could load that on a calculator".
I was wrong. Load time was an abysmal 14 second(!) wait. I normally don't make jokes on HN but today I'll be pouring out a sip of dark roast for my metaphorical 'dead homie'.
c2.com being a tragic example of this.
