The integration of Twitter and Facebook onto Xbox LIVE was announced this summer at E3 some months ago,
the launch came out today.While the Xbox LIVE experience is already one marked by advertisements, not only for games but also partner companies like Netflix, it's not a stretch to speculate that this is another channel through which advertising will approach the gaming market.
Facebook already hosts targeted ads, and Twitter's announcement several weeks back about the upcoming ads in the future make it hard-pressed for me to imagine that these features would be offered for free, sans-ads, on such a huge commercial giant like LIVE.
