In the Career 2.0 presentation I often tell people about blog aggregators. A small subset of developers are familiar with them, but most aren't. So let me point you to JavaBlogs.com.
The front page of Javablogs shows postings as they scroll by. Someone blogs, and they've registered their blog with JavaBlogs, and they make the front page. But the next posting scrolls them down, and so on.
The postings that look interesting get clicked. Get enough clicks and you end up on the Hot Entries page. I find the Hot Entries page is a great way to see what the Java community is interested in today.
If you haven't added your blog to JavaBlogs, I'd really encourage you to check it out. It's a great site to get your blog pushed out to thousands of developers all over the world, and it's also a great site to keep your finger on the pulse of the industry.
