The following video is from Monday's MarketFoolery podcast, in which host Chris Hill, along with analysts Andy Cross and Jason Moser, discuss the top business and investing stories of the day.

What had first been reported late last week is now official: Yahoo! (NASDAQ:YHOO) has bought Tumblr, the popular blogging platform, for $1.1 billion. Did CEO Marissa Mayer overpay for Tumblr? Is this a better move than Facebook's (NASDAQ:FB) acquisition of Instagram? In this segment from MarketFoolery, our guys analyze the pros and cons of the deal, why investors shouldn't expect returns anytime soon, and why Tumblr's bloggers are the most important people to watch over the next few weeks.

The relevant video segment can be found between 0:29 and 9:07.
