@Helen427, I'm with @Ruthie12 - I'm not a fan of the chronological order being messed up. As folks have said on other threads, some people have 3 year old reviews showing on their first page, which doesn't help travelers much. I expect that's a piece of code that's messed up with the change and will be resolved. Since this initiative keeps disappearing and reappearing, it seems they're still working on it.
Regarding the bold text, I kind of like it. I do have one review that is kind of famous within my family though, where the guest called me a "stud", which we find bizarre. I take a lot of rucking about it around here. Wouldn't you know, that line in the review is bold. I guess the algo finds it complimentary 🙂
