TITLE: Introductory text on geometric group theory?
QUESTION [45 upvotes]: Can someone indicate me a good introductory text on geometric group theory?

REPLY [5 votes]: A book I completely appreciate is
"Geometric Group Theory", by Clara Loh.
It contains 250 exercises of varying difficulty including programming tasks.
She introduces the key notions from quasi-geometry, such as growth, hyperbolicity, boundary constructions and amenability.
