I've seen a trend where users will choose to leave the forum, and just delete all their threads. If I post something in your thread, I didn't post it just to help you, I put in that time and effort to help anyone who might be helped by reading it, not just YOU. So if you just choose on a whim to delete all your threads, well that kind of destroys the entire point of having this community, not to mention the search bar. I can't imagine others that put more effort in than saying "good luck" or the like, don't feel the same way. It's akin to being in a jungle tribe where the whole group pitches in to build each others' houses, and then one of the families chooses to leave the tribe and they figure they'll just light their house on fire, so no one else in the tribe can use it. If you want to delete (or better yet just modify) certain parts of your journal or threads that YOU wrote, fine, I absolutely can understand. But when it's not just your content that gets deleted, I have an issue with that. I don't know how others feel about this, but it certainly makes me not want to post in other peoples' journals or threads, and that's kind of the point of a forum, isn't it?
