Why not add dates of learning/mastering to skill pages?

[duk]

So you can see easily when you started learning, when you were more or less active, how long ago did you learn/master a specific skill etc..

This data already exists and showing it next to the learned/mastered boxes shouldn't be a problem.. just an idea.. ;)

It could be added in the black drop down, which is exhibited when you pass the cursor above one of the skills you have on your home page.
