I disagree - I think my method of queue and nzb management is very useful, the only hit is that you need quite a bit of memory (2gb works fine).
I browse headers in live newsgroups using x-news every few days. If I see something interesting but not sure I want to download it just now, I create a nzb and import it to alt.binz as paused. Then it's there as a reminder that I might want it some day, and alt.binz keeps it in the list and keeps updating it's age for me, so I can keep tabs on it. Once in a while, I'll sort the list by date, and then look at the oldest ones, and if I really still want it and it's getting close to 200d, then I unpause it, otherwise I delete it. Once it's downloaded, I cleanup the queue. As I said, this works very well for keeping things under consideration if you can't necessarily make up your mind at the moment whether you want it or not.
If I don't import it, then I can't keep tabs on it's age because it's just a dumb file sitting in a folder, and I'll invariably forget about it.
