Article on ELT Blogging
You can now find the first article 'Why blog?' in the documents section of the ELT Weblog group at British Council - SearchEnglish , as well as discussion forums relating to different aspects of blogging in ESL & EFL.
Search English is a British Council "news, information, and networking tool for English language teaching professionals.' Apart from offereing discussion groups on all manner of subjects (CALL, online learning, blogging, etc) it's a free service, which you can configure to bring you the news / lesson plans / articles / etc. that you are interested in. If you haven't visited it yet, then I recommend you do so.
