Support for public Pownce notes has been added to TwitKu.com, the popular free social network mashup. Now you can monitor Twitter, Jaiku and Pownce feeds all in once place!
Pownce is still working on implementing an authentication scheme for their API, so notes send to only friends (i.e., non-public notes) are not included in the feed. Moreover, authentication is also required to post notes, so that will be a future TwitKu feature as well.
