Speaking with maelcum on #kde-devel we found out that KDE web shortcuts are a bit out of date since for example they don't have yahoo nor bing so we thought updating the list of KDE web shortcuts would be a good entry project for someone that wanted to start contributing to KDE.
You can find the current list of KDE web shortcuts at http://websvn.kde.org/trunk/KDE/kdebase/runtime/kurifilter-plugins/ikws/searchproviders/
Once you have a proposal come to #kde-devel in irc.freenode.net and hunt for maelcum or me (tsdgeos).
