Cons
Con Quality varies
The quality control for the content offered is fairly limited. As there are so many different instructors offering courses on Udemy, many of which lack formal training and teaching experience since anyone can be a teacher on Udemy, the quality varies quite a bit between the different courses.
Con Most courses are expensive
While Udemy does offer free courses, most of them are around $100.
Con Difficult to take multiple (10+) courses at the same time
The system becomes messy and hard to follow if you plan on using the site to learn more than a handful of things at once.
Con Only the most commonly used languages are covered.
C++, Java, JavaScript, C#, Python, SQL, PHP, Swift, Ruby, JQuery, HTML, CSS. You won't find anything less common like Haskell, Erlang, Elixir, Common Lisp, Scheme, Clojure, Rust, etc.
Con Limited usefulness for intermediate or experienced programmers
No advanced coding challenges. Look for those on other sites like hackerrank.
