Lest you think the return of summer weather has people flocking only to Zeitgeist, there are two meetups worth mentioning on the social web front this week that may make being inside (temporarily, of course) worthwhile. Tonight’s Chomp Tastemaker Party at Sloane on Mission sold on quickly, for which you can thank a Rose/Scoble duo. And tomorrow Ubergizmo will be hosting Digital Summer, their annual combination of photography, tech and fashion at Temple (think gadget demos and eco-fashion by Edun). Hot stuff.
