Crikey has started the most ideologically-eclectic blog to date, The Stump.
On the classical liberal side, it has Jason Soon, Charles Richardson and Chris Berg.
Also from somewhere right-of-centre is Counterpoint presenter Paul Comrie-Thomson.
On the left it has Guy Rundle, Phillip Adams and Andrew Bartlett.
The blogosphere (or at least my part of it) has been rather quiet the last few months, so perhaps putting this lot together will liven things up.
