It is very nice.
However, many times it takes 2X longer to function.
(Sometimes, it functions at its original speed.)
And, if it hits one bottleneck, it slows down to a snails walk.
They might be offering added-on features that maybe a small amount
of people might be interested in.
I think it is the "domains for sale" and the "alexa related sites" that is
drastically slowing it down.
I wonder if the site is archiving the data with each search? So, it doesn't have
to search out each category with each search.
