What does Hit Tail Do ?

Now I have hittail on my blog for nearly a month. What it does it do ?

• Collects all the search words used to reach the website.
• Segregates the keywords into Longtail and non-Longtail. Number of occurrences does not seem to be deciding factor as some key words one occurence were also classified as non Long tail keyword.
• Using the non-Longtail key words it suggests topics for blogging.

In the last one month it found 49 unique search words for my blog and suggested 2 topics to blog about. The topics were blog template classic, blogger widgets. This is supposed to be arrived at using some complext algorithm. I feel that this can be a good complementary service to the existing analytics service and Its a crowded space with most of the analytics service differing only in the way the show the data.
Here are the keywords collected and their classification. Its not the complete list.
