I think the solution (or at least a big part of it) is the resurgence of real blogs. When real developers write deeply technical posts about their experiences, on their own sites, everybody wins. Discovery is an issue, but there have been a number of HN threads recently on ways to mitigate this. Webrings, blogrolls, RSS... there was never going to be a super-convenient or efficient way to generate a high-quality, high signal-to-noise ratio set of sources. But curating your own preferred set of such sites, and making a habit of taking and publishing dev notes on your projects, and participating in the blog revival, is a step in the right direction.
