I have been frustrated trying to decide whether I should start a blog or continue writing articles for SqlJunkies.com. The reason I don't like blogs is that there is no barrier to entry. Anyone can write anything and post it on a blog. Is it worth reading? No matter; it gets posted on the vast Internet anyway.
When you want to publish to a magazine, even an on-line magazine, there is an expectation that you have done a good amount of research and testing before publishing.
So, I plan to continue to write for SqlJunkies, but I have now caved and started a blog. We'll see where it goes.
