I'm my opinion every thread is alive and is no different than any other as long as it's not closed. People these days prefer only posting in the threads that are only in the first page and don't even bother to look through other pages. That's why I don't see any harm if somebody revives an old thread no matter how pointless his/her post is, for all we know, that might attract others who got more to add than "i think so too".

For instance, take the global warming thread. It's dead right now and somebody revives it by posting something like "Global warming is bad". Sure the post doesn't contribute much, but the thread is back in the first page and somebody else might notice it and contribute with a much better one that will bring the discussion back, thus making the thread alive again.
