Seeing some of the posts about books brought an idea to mind. I have several technical books sitting around that are either not relevant to me anymore or I've already read them and the only thing left to do is donate them to the local public library.
The idea that came to mind was organizing a book exchange among dev.to members. The list of books could be another profile page item and folks willing to exchange books could then send requests and arrange a trade or a donation.
The exchange could also happen through another site if people know of good places where I could do that then please leave a comment. I suspect I'm not the only one that has a shelf full of books that are just collecting dust.
