It was only recently (in beginning of 2014) that I began to add my anime and manga to the list. Many of these may have been read or watched years ago.
I don't watch a lot of anime, but recently I am going back into watching anime and reading manga again after finding some anime that caught my interest.
There are some series that I liked but couldn't sustain enough attention or interest to continue them, so I dropped them. It does not mean that they are bad though. If I dropped them because they are bad or do not meet my expectations, it will have a score lower than 5.
