If you’re interested in trying out the Ping.fm service, which allows you to update multiple microblog-type sites in one fell swoop, you may want to visit the Ping.fm sign up page, and use the code “tastyping”.
I’m not sure yet if I will be using this much; I rarely want to post the same thing to every site I use… and FriendFeed’s aggregation of other sites also makes this a great way to have a lot of duplicates in some areas. But for some, it may be useful.
What do you think of this sort of thing?
