Though talking to people online about books - several different places and it's changed over the years. It used to be more focused on crime fiction, now I use the website LibraryThing and chat to particular people on there. I also use Goodreads but I prefer the conversation on Librarything and also while both sites are started in the US and dominated by American users, it's easier to record what I've bought, borrowed, read etc on Librarything so my book info looks how I want i to!
My sister started a FB group for friends and family members (including friends' mothers or friends of an older generation - one of her best friends used to live next door to her when we were all kids, and that friend and her mum are both on the group.
I have old favourites, series that I like to read though in some cases I'm very behind and in other cases, for example, I've really enjoyed the first two in the series but not (yet) got much further! But I'm also always on the lookout for new ideas.
I also borrow lots of books from the library, huge Kindle wishlists etc and scour all the daily monthly and other details and keep an eye on prices of books I'm interested in and buy from charity shops and secondhand.
In short, my problem is not being short of ideas on what to read, it's being spoiled for choice.
Good luck finding some good books to read though.
