Ive been running this for the past week on
www.thenailgeek.com and aside from some cosmetic issues (think the comments positioning is odd) - I cant say that I have seen so much as a peep from a bug.
Maybe I havent driven it into the ground, but theres at least 20 or so Journals with multiple entries and comments.
Oh wait, I did find a bug. I get a broken image next to the title bar when making an entry. I havent been able to be bothered enough to hunt down the root of it yet. An obvious show stopper (not!)
Anyhooo - my heart goes out to those having problems, but Its running pretty sweet here and I recommend it.
