It's been a couple weeks since Google announced its Friend Connect service, which lets you use the same login information to connect to several diffferent websites as well as track which of your contacts are using the same sites. It's too soon to tell if Google will beat Facebook's similar Facebook Connect service, but it's just managed its first big victory. Twitter, a website that lets users share with one another quick mini-blogs or status updates no longer than 140 characters long, has signed on with Friend Connect. Of course that means you can log in to Twitter using your Google password, but it also brings with it Twitter's superior friends list system.

Google's contact management system somewhat haphazardly lists all the people you've ever corresponded with, while Twitter takes the Facebook or MySpace-esque approach of only showing people you've specifically approved as friends. That means it should be easier to sort through the mess of contacts to find out what the people you really care about are doing around the web, although Friend Connect still doesn't work with many popular websites.

The two services are both about fostering relationships and communication, so they're natural allies. Neither Twitter nor Google have said anything about this deal being exclusive, so the former might integrate with Facebook Connect eventually as well.
