Even if you don't get really into tea you might just try making a cup of tea with hot water instead of boiling water and only let it steep for 2-3 minutes (ie. don't just leave the bag sitting in the cup while you drink). I've found that it can give the tea a better flavor with less bitterness. There certainly is a whole world of loose leaf teas to explore, but at the same time, it's plenty possible to make a really good cup of tea from a standard tea bag.
