Me? I'm using Chromium on Ubuntu Natty. The person you were suggesting should adjust his/her monitor? No idea.
To me, the site appears to be sponsored primarily by the Visitacion Valley Playground, whose name appears in much clearer print than FHI or SIAI in the banner. The FHI diamond appears immediately below the Visitacion Valley Playground name; the SIAI logo appears drifting below the banner.
Here's a screenshot of what I see, mildly marked up. I have no weird font settings or browser configuration so far as I know; this is pretty much default.
But then, I gripe about flaky experimental web sites all day. Don't worry too much about it. :)
I don't see anything about a playground. Please do post a screenshot, thanks.
I saw some discussion posts earlier talking about a LessWrong redesign, and now that things look different, I guess that it's been implemented. I'm always slightly annoyed for a while when a site I use gets redesigned because I have to relearn where everything is, but it eventually wears off once I'm used to the changes.
My initial impressions:
"Hmmm... it seems like the category menus have been replaced by dropdown menus. It's not like I used many of them anyway."
"Okay, I've clicked my name to see my recently posted comments. Now, where's the link to see it in context? Oh, I guess I have to click that icon in the lower right corner. For some reason I was looking for something at the upper right of the comment box."
"Well, that worked. Now how do I click to the parent comment? Oh, wait, it's probably one of those new icons in the lower right corner. I'll just mouseover them to see what they do..."
::realization sets in::
"AAUGH! LESSWRONG IS USING MYSTERY MEAT NAVIGATION!!!"
So, what does everyone else think of the new redesign?
