Yes sometimes it's overused. But when I use 'love', I mean it. We can use like instead of love.

 Yes in someways, but it's the true meaning people are loosing. When I think of love I think of loving someone so much you would die for them, love them so much that they are constantly on your mind and you are putting them before yourself. I also think of honesty, respect, faithfulness, kindness, communication, trust and other things.

 Perhaps it is overused, because in the English language, it seems there are few words which convey such strong emotional attachments--whether romantic or ethereal or material attachments--and all of the dimensions of same. The language usage is being adapted through that overuse, it seems, and through that usage it appears we as English speakers may be becoming more adept at the subtleties that help differentiate the word. This still makes it sometimes difficult for ESL speakers, however.
