I just read the very good paper on Alexandre Passant's work on their SMOB
project [1]
"Rethinking Microblogging: Open, Distributed, Semantic" [2]. Sadly that is one
of those papers you have to pay to get access to, making a great document less
available in the process, sadly.
(I have CCed Alex, so you can perhaps get a copy of it from him directly)
It should be a good project I think to do an implementation of SMOB in
Clerezza, as part of the project of creating a blog engine for it. That should
both help grow the SMOB community, and provide feedback and new views on the
implementation.
