Fund Alarm is a great site as it makes a simple, visual presentation for folks who do not have the time or ability to do deeper research. I do not always agree with some of the findings, VG Wellsley (VWINX) for instance gets a red rating for 3 & 10 yrs because of the index they compare it to. But I don't really care about that index, I like where Wellsley fits in my 'portfolio' (my wife's, actually) and the sleep at night factor.
But avoiding the worst funds is a good idea and they become visable on the site. Like the earlier responders asked, what are your comments on the site.
