I think one thing that I probably undervalue is the amount of materials available from Pro players for example on YouTube. Michael Redmond has been putting up Go problems a lot on Twitter, but he also makes short videos solving them on YouTube.

144 Go problem videos so far about 2-3 mins long each.
That and the other content on Joseki, game reviews and the alpha go material for the next book that he posts is great.
Of course there’s more great YouTube channels too
Also the AGA channel has a lot of good content and the Egf one that posted the twitch commentaries from the euro pro league.
Spoiled for content (in English, well compared to many years ago I imagine 
)
