There have been some heated Edublog postings recently (links below) concerning the virtues and pitfalls of different methods for facilitating community development and discussion within the Edublogospere.  This is a 'community forum' discussion that addressed some of these questions:

- How can the edublogging community best help educators keep up with the steady torrent of new educational tools, methods, and resources?
- What are the relative merits of blogging independently vs. being affiliated with a particular social network?
- How do we balance self-promotion and commercial interests with our participation in projects for the common good?  
- What, if any, expectations are there for 'professional decorum' in edublogging?
