Google adds easier Check-in and Ratings to Maps. Foursquare can’t be sleeping easy.

Google really is the new Microsoft. It used to in the ’90s that every good startup idea got squashed or bought by Microsoft. Now it’s Google’s turn to stomp any potential threats. Foursquare’s check-in concept is quickly being replaced by Google Maps check-in and you can bet this is not the end of it.

Remember: Google the is the Microsoft. Microsoft is the new IBM. And Apple is the new Sony.
