I still don't write a typical blog, as it was actually intended, rather than misusing it to persist ideas or as scratchpad. ...and this happens mostly in plains, trains and especially in starbucks.
Many of the ideas were reused - I gave several (JUG/conference) sessions and workshops based on posts from this blog. The next, blog related, talk will be at the OOP in few weeks :-). Actually my first softskills related talk ...and probably the last one.
Even my current book (not entirely completed yet, but it will come with about 60 Java EE samples and applications - I plan to publish the majority of the examples on this blog - of course), was initiated by this comment (I had to slightly change the title :-)). I will send Roberto a copy of the book. For some of the posts I received emails from interesting people, meeting them later at JavaOne, Devoxx, Jax or Jug meetings.
I'm thinking about implementing better stats for Rollerweblogger now :-).
