I think half the world has read it by now ... so yes I would read it on public transport or anywhere else I felt so inclined. I have never been concerned about what people think of me ... if they want to judge me, it is their issue, not mine.
Well, the cover doesn't look that bad, but a lot of people know what the book is about. I don't think I would read it at all, but if I did read it on public transport, I'd probably want to use an inconspicuous dust cover.
havent read it and have no interest. am part of a book club and we spend our time reading much more interesting texts. I dont think its an issue though. I'm sure the books serves its purpose for some and there is that unspoken rule about some level of personal space on public transport, particuarly with the whole screen thing these days, so so problem. brings a whole new idea to the daily commute.
If I wanted to read it I wouldn't have a problem reading it on public transport. However, from the crits I have read about it, sounds like a really turgid, badly written book, so wouldn't read it for that reason.
