Nah, from what i've observed from similar systems, people often rate based on their interests. The thread itselfs may be jolly good, informative and have no coffee jokes, but if 75% of the members aren't interested in guitar hero, it will be rated trash. Rating systems like that can be misleading and doesn't really serve a good purpose overall. If people learn to make correct titles on their threads, people who are interested will check it out no matter what rating it has.
