Thinking about Mo’s return, I

Thinking about Mo’s return, I was wondering – how many people have given up blogging successfully? By that, I mean how many have succeeded in not starting to blog again, either at the same site or in some new guise, once they have stopped publishing to a well-established blog?
And what does that say about bloggers and blogging?
(And I’m not getting into what does “blog” mean – I’m just using at as a generic catch-all term to describe any frequently-updated journal-type site).
