I preferred when there was a prominent, single-click link from the main page to recent comments. It's always been the main way I've navigated the site, and I think it may have helped draw people to the site's content, much of which is in the comments, including comments on top-level posts that don't in themselves look interesting.
It's an oversight - we'll fix it.
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 it seems like the category menus have been replaced by dropdown menus.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?
