While the tidy-verse and data.table are definitely game changers for R, it's still worth learning the basics. Often the packages make irritating tasks easy, though they rarely touch the tasks that are easy in base R. I've seen some pretty convoluted dplyr from newcomers that could have been achieved in a single line without loading any packages.

Course author here; I agree about most of the lessons being outdated in the last two years, and that R for Data Science is a great modern source.
I'm working with DataCamp to develop an R course that covers dplyr, tidyr, and other newer additions to the R language.

Took me a while to find the Trump Tweets blog you referred to. It is here for anyone trying to find it:
http://varianceexplained.org/r/trump-tweets
By the author of the tutorial, not the poster of the link.
If you are interested in learning R, you may want to read the R for Data Science book (http://r4ds.had.co.nz/) book by dplyr (and ggplot2) author Hadley Wickham.
Relatedly, I have my own (slightly more complicated) notebooks using R/dplyr/ggplot2, open-sourced on GitHub, if you want further examples of real-world analysis with publically-available data along the lines of the Trump Tweet analysis:
