So I did something smart several weeks ago (blind hogs, acorns, and all that):
I added tofugu.com to my RSS feed in NetNewsWire. Now I know whenever they post a new article. The latest article on 懐 was a great read (though I’m slightly miffed that WK itself only teaches the 懐かしい vocabulary word).
Sadly, RSS never really caught on for a number of reasons, and only old techies like myself still use it. NetNewsWire only recently became useful again. So I doubt that RSS/NetNewsWire is a reasonable option for most people here.
I’m wondering if other options are possible. Two ideas:
This discourse site makes it easy to subscribe to updates in threads you find interesting. It would be nice if there were a thread that was only updated whenever tofugu.com posted a new article. (If it exists, I’ve not found it.)
I (or someone more qualified) could try to write a dashboard userscript that notified of any new articles posted to “followed” Japanese language blogs (especially tofugu.com). Effectively a mini-RSS feed widget.
