@Impervious: That part about disagreeing is simple. I personally take psionics as just one system, one branch of Magick. Magick itself is a huge world and as they are people with different professions in real world, there are practitioners within different systems in Magick.
Some do their working directly through their Selves, some uses supernatural beings, deities, God, planetary correspondences, etc. That's the first root of the argument. Second root of the argument is reason for practice. Some people practice to ascend to higher planes, some people practice to improve their mundane lives.
Let's assume we have a technician and an artist and they both are going to bake a pie. Although the result is a pie, they will use different process. Technician will go by strictly following the receipt, artist will try to customize the process as much as possible, giving his individuality to it. They both are going to make a pie but they don't agree with each other about the process. It's the same with Magick.
@Trowa: You answered your question yourself, didn't you? When someone smites or applauds you, was it because of your current post or because of post you made a month ago? When having a data regarding individual posts you can easily conclude what is good and what is not (for the community, not overall).
I personally prefer publishing on my blog now as Blogger gives full statistics of people reading my articles. I can see which articles is the most favorite of the day, week, month, year and what searching keywords were used to find my blog and I can react to it.
