In Japan: an otaku is someone without a social life whatsoever and is an insult of the highest regard. There is a negative stigma associated to the phrase otherwise that involves a Japanese murderer who killed women because "they didn't have smooth faces like women in anime."
In America: a badge of honor worn by fans of anime, in lieu of simply calling themselves anime fans. Overused slang that has lost its meaning to many fanboys and fangirls.
In Japan: "With the amount of pornography that man buys, it's no wonder they consider him a disgusting otaku."
In America: "Dude, I love Sailor Moon and Utena because they have lesbians in it. I'm such an otaku! ^___^"

there are several definitions of "otaku"

1) polite(correct) way of saying house
2) many people mistake the actual definiton of otaku when it comes to things such as "anime otaku" or "game otaku"
it used to be a insult but recently, the definition has changed to a more positive meaning, although the word can still be used as a insult, it is more commonly used as a compliment
Ex. anata wa computer otaku desu ne (your a computer otaku)

although it is unclear as to when the definition switched, many believe that it may have happened with popularity of animes and mangas going up
