For those who like no-frills, starkly presented information, this site may beat out even the Mayo Clinic's standardized, text-dense pages. From the National Institutes of Health, it's just what you'd expect from a government agency: authoritative information made as boring as possible. In addition to all this, it's not as comprehensive as it could be, but with this style of presentation if they added any more information, there's no way I could make it through it all.

I really like this straight-forward page on treating asthma and that it includes children and older adults.
