WHY, why would you farm this out to the cloud (i.e. "someone else's 
computer")? We have more processing power in our pocket than the entire world 
had available in the 70's and URL parsing is farmed out to the cloud? :|

Seriously though; it must have gone something like this:
- Dev A: We gotta underline links, but I don't know how to do this.
- Dev B: Use the cloud, man, the cloud is where it's at these days. Just see 
if the domain name resolves by firing off a DNS request and then if it isn't 
NXDOMAIN, you're golden. 
- Bearded Dev C: But guys, have you thought this through...? Have you 
consid...
- Dev B: Dude, don't be, like, totally a bore man... Cloud, didn't you hear? 
CLOUD! You old farts are always trying to keep us yung'ens back.

... and lo...

I weep... I weep for humanity...
