+1 for this. Regarding to the place to hold blogs. Personally, I prefer to use existing blog and separate by tags/categories and title names. Because, the dev blogs are very good learning materials. I believe many users will be interested in these posts. It's just like "Technology Deep Dive" talks in Flink Forward which attracts many audiences. Putting them with main blog together can help to give the dev blogs more exposure.
But I also share Robert's concern. So I'm in favor of Ufuk's idea: starting with Wiki, and moving good posts to the main blog gradually. We should also improve our current blog web to support tags/categories. Maybe @vthink...@gmail.com <vthink...@gmail.com> Yadong can help on this.
