Yeah I go back because its fun and intriquing to read others post, or see others images/videos. Sometimes its fun to read the flame wars but then it reaches an annoying point when it becomes futile. Then you have to start ignoring certain folks and jump onto a new thread. Yeah many of us guys with nothing else to do use RJ to make up for our boring social lives or lack there of. Some try to deny it, but everyone wants some form of attention. Guys on RJ who reply a lot are super eager to "go back" to see if there are any more replies.
As for me, if I was employed, had a bf, had a large friend/social group I could hang out with every other day... oh this account would only be used for reading fitness tips.
