You know, I just went to EF thinking you guys were probably just busting his balls a bit and it would only have a piece here and there that looked like SP, but DAMN. I have to give kudos for the Vbulletin tweaking, but why in the world would you rip off a layout/design like that knowing you're going to get berated about it? They copied things right down to the ad design like on the main page. I was just looking at that on Sitepoint yesterday admiring how they constructed the ad and how it reacts to different browser sizing. EF did the same exact thing.
While it looks pretty cool (well, it's Sitepoint!) I have to shake my copycat finger towards EF on this one. Shame fer shame.
