And? What's your point? Have you an answer for the question?
 
This has nothing to do with the MBA, it has everything to do with the way the site is programmed.

It happens on every single computer out there. Oh and it's not your MBA slowing down, it's just Safari. If you actually switch to another app while it loads, you'll see your computer is operating just fine.

I'll see your 9to5 and raise you www.cultofmac.com I can't believe all the crap it tries to load (but can't due to NoScript with Firefox). Not to mention that Malwarebytes gives me a popup warning every time I load their site.

Well that page loads and scrolls very smoothly with only AllPagesZoom, AdBlock and ClickToFlash loaded in Safari. The 9to5 site is so bad my new 13" MBA i5 can't hardly scroll at all. My 2.2GHz C2D windows laptop (which has a discreet graphics card) scrolls it easily once the page is loaded).
 
I do have Adblock running in safari and it's still bloody slow. The answer I questioned wasn't clear in it's message as it looked like you were having a go at the forum. Sorry for mix up.
 
I rechecked and I'll give you 9to5 as the winner. NoScript reports that 9to5 tries to load 203 scripts. Cultofmac is "only" 171.

Some others:

Engadget 37
CNET News 26
Appleinsider 24
Padgadget 31

Why the hell do 9to5 and cultofmac need so many scripts?

Adblock in Safari doesn't block many of those by default and has to be blocked manually.
