[jdom-interest] Downloads.....

Hi All.

In concept, I agree with you, but, honestly, the 500 is better than 5 
argument is exactly what interests me. I am looking at relative usage.

Also, 'sonatype' (the maven gateway I use) now has the statistics page 
up and running.

For example, here's the usage graph for JDOM 1.1 from maven (you can see 
that JDOM 1.1 usage is actually trending *up* ... :( I don't understand 
that, honestly. ):


Here's the graph for all jdom2 artifacts:


What's interesting is seeing that maven users have not been finding the 
jdom2 artifacts:

Here's the graph for 2.0.2 which is the last version posted to the jdom 
artifact before I was convinced I had to move jdom 2.x versions to the 
new jdom2 artifact....


Now, compare that with the previous version 2.0.1 ... see what happened 
when 2.0.2 was released?


You would expect something similar from 2.0.2 when 2.0.3 was released 
...? But you can see that the 'tail off' is simply not there in 2.0.3... 
basically people are not looking at artifact jdom2 the same as they look 
at jdom.

Anyway, download statistics do add some value, whether is is just trend 
information, or for 'warm and fuzzies'.

Also, maven-central keeps relatively convenient statistics... which is 
possibly the best thing about maven ... ;)
