The aquisitions of Scout Labs, Biz360, and Filtrbox so far this year have people talking about what else is coming. Actually, I count seven acquisitions so far this year—apparently we need a score card.
If you weren't aware, I post industry news at Social Media Analysis. If you care about what the companies in SMA are doing, you should read it.
The M&A list is at SMA, too: Acquisitions in Social Media Analysis.
