How do I discover things on the web?
For me it's never technorati or whatever other rating system or whatever catalog to discover new blogs and authors.
The links on twitter from the people I like, the links in other blogs from the people who I actually read and whose opinion I value, and from some aggregators dedicated to the particular topic (it may be a blog planet, a livejournal community or some other on-topic community blog, or social link exchange like news.ycombinator.com or some subreddit). Last but not least I discover a lot of good things from the people I actually know in person. The technology doesn't matter much here, it is the people who care about some topic. Where two or three come together to discuss the same question, invariably there are some valuable links around.
