This is how I manage it:

• Usually I add feeds of blogs I find out from other aggregators (people posting links, HackerNews, Lobsters, Kotke.org, etc).
• This website categorizes blogs, I found some really good gems there, so I follow their feed.
• My RSS reader of choice (Inoreader) can show trending topics from feeds I am not following.

I use Logseq as well, and I love it. Something about journaling bullet points fits me so well and feels natural. But, templating system is a bit clunky, the app is rather unstable (do enable git tracking or you might lose your notes), themes/plugins quickly get out of sync and to fully power-use it you need to know Clojure programming lanugage (I don’t and I’m missing out powerful filters).

But, all your date is in simple markdown file, so we are not locked in.

I use Tree Style Tab for vertical tabs. Clearly one of the best things one can do for browser productivity.

I use CamelCamelCamel for Amazon. Besides price history it allows notifications on sales or price drops.
