CNN reports Facebook has acquired location check-in service Gowalla for an undisclosed sum. The move would represent an escalation of Facebook's ongoing efforts to compete with rapidly-growing market leader Foursquare, which closed a funding round in June at a reported $600M valuation. Facebook aims to make about 20 acquisitions in 2011, up from 10 last year.
