I got my first girl friend, mini project approval in college and many more from that gtalk. I was devastated to know it was discontinued. They could have just named hangouts as gtalk and released it. Which would have been a good effort. Companies work so hard to create brand value in their products but Google unintentionally creates value and destroys them later on. Phew.
Then a lot of people would be claiming Google was being dishonest and tricking its users.
