A tag cloud for Geoblogosphere News

Geoblogosphere News, has two new major features:

1. A 'tag cloud' shows a list of the week's most frequent terms you used in your blogs. As this list would have been useless without the possibility to click on a term and get a list of corresponding blog entries I also added
2. some search functionality which allows full-text queries on blog.

This week's hottest geoglobospheric topic seems to be Darwin..
