Although we cannot say that Google will close it because many Google reader lovers are against this move and they are doing what ever they can to make a turnover. According to Google they will be ending the service from July 1, 2013 and if they do close the service this is a good time for other services to catch the space. The best service I could think of is Feedly and in a recent blog post it has promised that it will be getting in some more servers to be the next RSS service. At the moment it is not yet ready to take that server load but Feedly at the moment looks to be one of the services that could take advantage of Google Reader's death. Other services like Pulse, Flipboard and some more are also in the queue.
