That post both advocates for TLS-everywhere (which I support) and thinks it would be beneficial to drop HTTP Keep-Alive... Aren't you concerned about the latency hit? TCP has 1 RTT to setup, TLS has 1+ RTT to setup.

Also, TCP's congestion window grows over time; with your proposed model, you'd continuously open connections with tiny congestion windows, rather than a few connections with growing congestion windows.

I think all it'd take to change your mind is to load Facebook or Twitter with SPDY and Keep Alives turned off...
