The purpose of the widgets on this site is to show potential clients what Jelle is worth and to show off a little bit ;). It took him like 15 minutes to get everything set up on his site, so basically no time. He used the skill chart on the site to give a quick overview of his development over time. Then below that chart, the summary widget is used to provide an excellent summary of the programming languages. At last, he used the activity widget so he can show he is still actively developing stuff.
