This document discusses mash-up environments and two tools called ReScope and ReMashed. ReScope is a personal tool that mashes a user's Delicious tag counts with recent tags to create an interactive tag cloud for supporting reflections on bookmarking habits. ReMashed is a mash-up environment that allows users to personalize community information to their preferences by indicating which Web 2.0 services they use and contributions from others they like or dislike. It uses collaborative filtering to generate personalized recommendations by matching users with similar tastes.
