Brendan Tierney theoretically makes my life easier:
A regular question I get asked is, “is there a list of Oracle-related Blogs?” and “what people/blogs should I follow to learn more about Oracle Database?” This typically gets asked by people in the early stages of their careers and even by those who have been around for a while.
You could ask these questions to twenty different (experienced) people, and you’d get largely the same answers with some variations. These variations would be down to their preferences on how certain people cover certain topics. This comes down to experience of following lots of people and learning over time.
Click through for a list of top Oracle blogs. I should probably check out some of them, though I don’t tend to do much with Oracle here. But if you do, there’s a starting point with 100 separate blogs to check out.
