I would like to introduce a “new” blogger to you. Joshuha Owen has restarted his blog and will be covering topics on business intelligence and data. I have worked with Josh for years at a Magenic and now Pragmatic Works. I look forward to seeing what he will be writing about in the future as well on Bits, Bytes, and Words.
Here is his most current post. Enjoy!
