We present a highly personal and biased review of the observational portion of this meeting. We cover Tiny-Scale Atomic, Molecular, and Ionized Structure (TSAS, TSMS, TSIS), emphasizing the physical aspects involved when the structures are considered discrete. TSAS includes time- and angular-variable 21-cm and optical absorption lines. TSMS includes the Heithausen revolutionary component called Small Area Molecular Structures. TSIS includes classical scintillation and discrete structures that produce Arclets, Intra-Day and Intra-Hour Variables, and Extreme Scattering Events. We conclude with reflections on the relationship of Tiny-Scale Structure to the Local Bubble, TSAS to TSIS, and the use of globular clusters as an illuminating backdrop.
