"Will the Promise of LBS Ad Models Ever Get Off the Ground?"
summary
Argues LBS revenue myths and gives concrete counterpoints: small businesses split into growth/plateau/lifestyle segments so conversion and time cost matter; geography precision often hurts monetization because AdSense auction suppresses geo precision; yellow pages/ad networks already scale local sales — AT&T Yellow Pages: ~$1B annually, Q1 ≈$210M — while self-serve is limited. Predicts a shift to pay-per-lead models and points to Craigslist scale, Constant Contact (250k users, ~$100M) and Twitter as proofs or platforms that might make low-touch lead delivery viable.
