One source of aggregator that I find useful is to subscribe to newsletter to a topic of your interested. Optionally choose weekly option to avoid daily email overloaded. Twitter is very good to keep up with latest trend and discussions, make sure to follow and trim following list to suits your interests best. Recent Twitter's algorithm changes seems make it less focused than before, but it still good. Otherwise, bookmark our own https://news.ycombinator.com/news and pin it to position 0 of the pinned list, so that everytime or everyday you open the browser, HN is default.
