"I advised you to dispose of your books, and advise it still. Be sure to do it, it will give you peace of mind.
But at the same time be careful not to become narrow-minded, or afraid of reading what is well written, quite the contrary, such writings are a source of comfort in life."
Hi, and welcome! Without knowing your friends I can't say whether they'd be likely to want to participate, but you could get started on your own and then show them some of your releases. I like to leave books in interesting or scenic spots - historical markers, statues, near flowerbeds in public parks, etc. - with photographs in the release notes; if you did that with a book or two, you could show the photos to your friends and see if they'd like to try it too. (If you get a catch, that might make things even more interesting, but there are no guarantees on whether someone will journal a book. Do browse the Site Watch forum for examples of catches, though; it might give you some ideas for releases, and can be reassuring if you don't get a catch of your own right away.)
