Top TR Websites

Both Charlie Dixon's TR/RT Directory and Alternative Solutions in Long Term Care websites recently listed the "Top TR Web Sites," using Alexa as thier source. NCTRC was the top website in terms of traffic, followed by NYSTRA, CATRD, and ATRA.

It is logical that NCTRC might have the most traffic. But it is strange to me that NYSTRA and CATRD would have more interest than the ATRA website. I wonder why this is so?
