Heikki Lehväslaiho has a nice series of 4 blog posts on how he takes notes with Org mode. He lists the first three posts in each entry but not the fourth; it’s here.
The last two posts are particularly interesting. He talks about how he takes notes from his Elfeed buffer and from his phone. Elfeed has some built-in methods for capturing links but Lehväslaiho’s method makes it speedy and easy. If, like me, you’re more interested in forming Org mode links, it would be easy to slightly modify his elfeed-link-title function to make the link and perhaps query you for the link description instead of using the title.
If you’re using an Android phone, Lehväslaiho shows how to get notes from the phone into an Org file using a package he wrote. Sadly, it doesn’t appear to work for iPhones
