 Welcome to Apache Mahout!
 
-Mahout is a scalable machine learning library that implements many different 
-approaches to machine learning.  The project currently contains implementations
-of algorithms for classification, clustering, genetic programming and
-collaborative filtering, all enabled to scale by leveraging the power of 
-Hadoop's Map-Reduce (http://hadoop.apache.org) implementation.

+Mahout is a scalable machine learning library that implements many different
+approaches to machine learning.  The project currently contains
+implementations of algorithms for classification, clustering, frequent item
+set mining, genetic programming and collaborative filtering. Mahout is 
+scalable along three dimensions: It scales to reasonably large data sets by 
+leveraging algorithm properties or implementing versions based on Apache 
+Hadoop. It scales to your perferred business case as it is distributed under 
+a commercially friendly license. In addition it scales in terms of support 
+by providing a vibrant, responsive and diverse community.
