I really need to follow this advice more, but sadly life often gets in the way.
I've been a book worm for pretty much my whole life. I've read many types of books over the course of my life, but currently the sorts of books I enjoy the most are fantasy and science-fiction. I particularly like it if these genre's are mixed with comedy like the style of Douglas Adams and Terry Pratchett. I definitely can enjoy more serious fantasy and science-fiction though. I also enjoy vampire books, but not quite as much as I did when I was younger.
I'm not going to add any books to my shelves that I read before 2012 just because I've read so many books in my life and it's difficult to remember when I read them and how well I liked them, and I'm sure there are a great many books that I've read in my life that I've completely forgotten about.
The editions that I have displayed on my shelves do not necessarily correspond to editions that I actually own. I generally just use whatever edition has my favorite cover which may or may not match the covers of the books I actually own. If I own more than one copy of a book, in most cases I won't have multiple editions displayed on my shelves. An exception to this would be collective books/omnibuses in which the individual stories are all available separately. In this case I will probably use the individual books for tracking my reading, but will display the omnibus or anthology just as a book that I own.
Because BookLikes does not have any suitable way to track re-reading books, I have created a shelf called "all books read" in which I will permanently place every book that I have read. Books that I am re-reading will get transferred back and forth between the official "read" shelf and the "planning to read" and "currently reading" shelves.
