Personal Learning Networks (PLNs) and Classroom2.0

Hi all,

After my brief exchange with Harry about PLNs and a great, informative conversation with Steve H, I was hoping some of you might respond to the following question:

How has Classroom2.0 enabled you to establish or extend your personal learning network into physical meet-ups and working relationships?
(such as meetings in local school districts, Classroom2.0 local 'workshops,'
or Blogger Cafe meet-ups, -- esp. keeping ISTE's EduBloggerCon in mind =)

Have you maintained working relationships across both virtual and physical, or do you favor one over the other once you've become a 'colleague' in CR2.0..?

Thanks much!!
Elizabeth
