All old threads should not be removed. They are meant to stick around so that people can find them and see what was said rather than start a new thread about a conversation that has already started or reached a conclusion. It saves everybody time if someone is, for example, able to get an answer to their question rather than having to start a whole new thread about it and wait for answers. This is a basic practice of pretty much any forum.
