It surprised me last night but so far I like the text in posts and comment boxes. I have trouble making visual sense of the front page below the fold, but I have the same difficulty with tumblr and pinterest, so I think I'm just old-fashioned, lol. Above the fold it's nice to be able to see the most recent posts without scrolling and the top level navigation looks really useful.
On the issue of losing posts in process when you go to another page, I write longer responses in notepad or Word (although I get all these weird line-breaks when I c/p from Word) and then paste them into the comment box. Alternately, like Suz says, I open a second version of the site.
My long term wish (which I understand probably isn't that doable given your search engine?) is for the search box to pull up results in date order with the newest first -- many times I want to check on something I remember reading or look up what Angie said about 'X' and need to look through several years of older posts with less applicable info first.
