Super duper awesome hats! Awesome variety of everything - shapes, sizes, colors, materials. Every hat has quite a detailed description and even if that is not enough you can get custom ones. Haven't tried them yet but I definitely will.
last.fm helps me find new music and to see what my friends are listening to. I really like seeing how my music tastes have evolved over the years and with the new year in review feature I will see who were my favourites every year with very detailed descriptions.
