Thanks for the blog post on this. I can't seem to get step 4 to work however because the Twitter publishing preferences link does not show up in my settings. Would this be because it hasn't linked properly with Twitter? I used my twitter account to make an account like you suggested.
@xairin: I think you also have to add your Twitter feed to your FriendFeed account. To do that, go Settings -> Services -> Add/Edit. Select Twitter, enter your Twitter username, and go from there. That *should* get the Twitter Publishing preferences to show up. If it doesn't let me know and I'll ask back at FriendFeed :)
@rachelle: I listen to a LOT of music every day too and so far only 1 follower has complained, but when I asked him if he preferred I stop he told me to carry on and hasn't stopped following me. I get plenty of @replies for the stuff I listen to. You'd be surprised how many people might find your tastes interesting. I think real-time scrobble streaming [i]a la[/i] Twitter is something Last.fm is really missing out on tbh.
