Google Reader gets a bunch of new features: “friends worldwide, tagging with note, alphabetical ordering, and even last-crawl-date”.

Friends Everywhere: Now that new and improved sharing features are available in the US, Google’ve made sharing with friends available to Reader users in all supported languages.

Tagging while Sharing and Noting: You can now add a tag while adding a Notes. This is especially useful if you use lots of tags to organize your posts, or if you have multiple public shared tags.

Sort your Subscriptions: You can now choose between alphabetical ordering or drag n' drop ordering for your subscription list, via an "Options" menu at the bottom-left of Reader's interface.

And, finally the team has exposed the date last crawled a feed in the "details" area, and made some iPhone speed improvements and bug fixes.
