#1810: Chat Systems

[An Euler diagram with many circle like drawings for various chat systems is shown. Some circles overlapping others in complicated ways, others are single circles with no connections, but most are embedded into others. Inside the circles mainly the standard sticky figures like Cueball, Megan, Ponytail and Hairy are shown but there are also a few others.]
