Well but I find it very atractive to see how many post I did and when I registered it somehow lets me feel like I really archived something.(or it just shows that I'm doing too much 3dgs stuff).
One Idea could be that you upload a small picture to every contribution you make.
Then when someone clicks the button "hey that helped me"
you can see this small picture in the users personal-page and if you click on that small picture you can get the link to his contribution URL and some information how many people klicked that button or donwloaded his contribution.

It would just caracterisize a persons "personal-page" you could just see "oh he's in to scripting/modeling/2d design and he's pretty good at it"
