When the Founding Fathers ratified life, liberty and happiness, they might not have quite envisioned Independents Hall. Low-pitched techno music echoes from the high ceilings of a loft-like office on Philadelphia's Strawberry Street. A smattering of 20-something guys (and occasionally women) sit intent at laptops resting on black-and-silver Ikea tables, occasionally stopping for a smoke, or to share info about software or gear. Under a side table, a box of Transformers action figures awaits a fidgety moment. Upstairs, sofas and a shower anticipate a late-night crash.
