I'm ok to add people.. but if they havent messaged or been online in a week, i likely just delete them. I'm more apt to keeping a person on my list if i hang out with them every once in a while.. (which there arent many of those).. not through lack of trying.. they just arent ever online or available, or even Im back... lol
why keep somebody on your list if they werent interested in being a "friend" right?
