Time will tell whether this helps things get better or not. You can see it as wasting the communities time (though also flaming others is a waste of time). But you can also see it as an opportunuty for the community to practice their skills and be helpful when the real thing comes around. We will have experienced people around who took the plunge for us - if you like it or not. Look at the interest for example in the thread about "what works better now" - almost 35,000 views. All these viewers will be around to help when the real firmware gets released. So OK maybe not every bug will still be around - but the accumalated experience will be helpful for the community.
