1. Collect yugioh cards: Have gotten some of the first set but got left behind on Magic Ruler to resuming in Lost Millenium. Created 5 sample decks of 70+ cards. TCG-wise, not all that good.
2. Music streaming: Mostly the mainstream music on radio or T.V. The web I find more mainstream on (some sites you already know) and foreign music via crunchyroll.com (not much on anime music).
3. Checking for updates: sites I check on - www.Serebii.net for all things Pokemon, Fightersgeneration.com for fighting game references, Gamefaqs.com (mostly checking their forums, check cheats and unlockables, and game data), and Gamespot.com for their reviews.
4. Anime streaming: Check past animes [cause some of this year's anime can get rather disturbing?!] several video streaming sites have these past animes (probably already know some)
