Personally, I forward everything from HN's front page, every tech-relevant subreddit, major tech companies and software projects, roughly 30 blogs, Twitter, and blogs/changelogs for every project/service I depend on (for work or side projects)... all straight into my email.
Rules automatically curate emails into prioritized / categorized folders. Setting up those rules was my solution to information overload - reviewing rule relevance is the same as measuring how my attention investment tracks against long-term learning goals.
One process for managing my work, personal life, and interests :)
10 minutes a day is enough to follow every personally relevant development. I do a deeper hour-long review of lower priority content at least once a week, but my email is an effectively infinite backlog of interesting-possibly-relevant information.
