Some of Oracle executives, for now from the Apps group, have started blogging - that you can check out at http://www.oracle.com/corporate/executive/blog/index.html
For now you have blogs by John Wookey, Cliff Godwin, and Jesper Andersen. These don't appear to be in the traditional blog format, and don't seem to have been updated in almost a month, but I still hope that blogging will be recognized and organized as a legitimate and important channel of reaching out to our customers and user community. I believer blogging, by being more immediate and less formal, plays an important part in reaching out to a segment of users who may not be adequately covered by the existing forms of communication. Product management and development have an important part to play here, so here's to a long and popular OracleBI blog!
