Maybe you should use conversion metrics combined with usage statistics weighted against trending and flow relative to feature enhancements and capabilities instead of any raw value against general hits?<p>Each business is different, and even then different areas of a product can have differing requirements and needs.  What is 15% for you, may be &lt;2% and declining for others.  My current and former positions see iPad users in greater numbers than any other single platform&#x2F;browser, as an example.  It may be better served to create features that work for the larger audience and other platforms easily supported than grasping at a fraying edge.
