Definitely interesting the trend that Google is following, first with iGoogle and now Reader.

With backstitch (http://backstit.ch) we get questioned a lot why Google is no longer supporting these types of services (and if this means there is no opportunity there since they aren't worried about it anymore). We honestly feel like there is a lot of surface left uncovered when it comes to personalized/streamlined content and it just doesn't seem to be part of Google's refocusing (this has been seen with the shutting down of a lot of their lab projects as well).
