Anatomy of Going Local!
These services claim 15-25% CTRs as opposed to 1% from traditional web space. If this is true a whole lotta money is going to move from traditional web budgets to LBS companies. However, this will not happen till the user base significantly increases from the current aggregate of approximately 6.5 million. If any of the biggies like, twitter, facebook or google crack the LBS game this could happen sooner than later.
