Since you're the one who is making a huge change to the article, and you have been reverted by several users now, maybe you're the one who should consider explaining your edits. (And the place to do it is on the article's talk page, not here.) I will say you are likely to keep getting reverted if you continue to replace information that has a good variety of reliable sources with information sourced to a wordpress blog. Self-published sources like blogs are not considered reliable. And even if you had provided a reliable source, you didn't explain why you deleted so much other sourced material. I suggest you open up a discussion on the article's talk page if you have suggestions for improving the article. Cheers,
