Typically I'll have tabs for my email, business (book marketing mainly), Zelda Dungeon's forums, Zelda Universe's forums, and Youtube, all these open for convenience and efficiency while I'm browsing the 'Net. Additional tabs are usually reserved for shows that I'm keeping up with online and watch in the evenings, since I can't stand commercials and TV advertisements in general, or Googling for quirky memes or references on Wikipedia, mainly. Everything else varies.
