The hullaballoo surrounding Facebook's IPO, the eye-watering $100bn headlines and the subsequent bickering, has largely passed by the social giants' 901m users.

Last week's launch of the App Center could make a much bigger impression and may prove a canny move in answering criticism of Facebook's slow progress in monetising it's half-a-billion (yup, you read it right) active mobile users.

If the IPO critics are to be believed, the company's valuation and its future is all about advertising revenue, but the App Center launch launch hints at a longer-term strategy. If successful, it could establish Facebook at the heart of the app ecosystem, as well as seeing the coffers swell with mobile ad and targeting revenue.
