When I first started Linux I did a lot of distro hopping. I really wanted to see what the Linux world had to offer in terms of software. In the meantime I've been through my fair share of distros and DE's. I've finally decided to settle with Xubuntu as you probably already know. I really like XFCE4 in terms of weightlessness and flexibility. Soon enough I'm going to start distro hopping once again, trying out the different distributions and DE/WM's to keep up with what's new in the Linux world. So my question is what's your favourite DE/WM?
