Friendfeed let’s you publish everything, or a few selected services to Twitter. If you have a lot of stuff going into your Friendfeed stream, you might not want to share everything on Twitter.

Sign up for an account on Friendfeed if you haven’t already got one. Import your Google Reader shared items and go to your Advanced Twitter Setting. Check the box that says ‘Post my FriendFeed entries on Twitter by default’, then select to share ‘The services I’ve selected below’ and put a check mark in Google Reader. Save Changes and your shared items will be republished to Twitter.

Link to the original source or the Friendfeed entry?

You might notice that at the top of the settings page, you have the choice of ‘Link to source site instead of FriendFeed conversation (does not apply to comments)’. If you don’t check this box, the link you send to Twitter will send your visitors to your Friendfeed entry. If you like me, want to encourage people to subscribe to your Friendfeed page you might like this. But for most people using Friendfeed only for this purpose, it makes sense to check it and send your visitors to the source.

Ryan has a great post on a more detailed strategy for sharing links, I encourage you to read it of you frequently share links on different platforms.

And… if you’re not too hung up on the Google Reader interface, consider installing Feedly into Firefox. It allows you to easily share stuff on Twitter, it even shorten the link.
