I would never recommend dribbble though, it’s glossy run of the mill boring stuff! You’d do better with dabbling in design history… My favourite design education text is the book ‘Thinking with Type’, which combines practical knowledge with a inspirational reading of typographic history, renaissance books, swiss grids, postmodern experiments http://www.thinkingwithtype.com/
That’s like saying that if you want to learn how to paint you shouldn’t be visiting the Louvre, you should go to a mediocre art fair instead! That’s not true, you need great examples at each stage of the journey.
