It's not as impressive as the $19 billion Facebook splashed out for WhatsApp, but Twitter still shelled out a respectable amount -- $86.6 million, to be precise -- for live video streaming broadcast app Periscope and social media marketing platform Niche, according to the company's filing with the U.S. Securities and Exchange Commission.

As everyone knows, the whole point of making cool stuff is to show it off to other people who are interested in the same kind of stuff to compare notes, get ideas, and of course, bask in their praise and admiration. The "maker" movement, a loosely defined enthusiast group covering a wide range of do-it-yourself gadgetry, robots, vehicles, toys, crafts, furniture, and idiosyncratic doohickeys, is now getting its own online forum devoted to the making and sharing of stuff, courtesy of Maker Media. It is called, appropriately enough, MakerSpace.

According to the Bureau for Labor Statistics, 53% of the total current and prospective workforce did not have a bachelor's degree in 2014. And in 2010, 58% of jobs were held by workers with a high school diploma or less, according to the Georgetown Center on Education and the Workforce. Thus, at least half of American workers had no options for online work-related social networking.

The new tools, announced this week on the Facebook Developer blog, will give publishers more control over the execution and management of native ads.

This probably isn't what they meant by a high-engagement adjacency. Twitter's Promoted Tweets were in the news for all the wrong reasons this week, following reports that ads from marketers including Nielsen, Duane Reade, NBCUniversal, and Gatorade had appeared next to pornography. "Adweek" first reported the news.

This week brings rumors that Facebook is interested in acquiring Nokia's Here for mobile mapping, a stepping stone to more location-based services for users and targeted ads for advertisers. TechCrunch reports that Facebook is on a fairly short list of potential buyers for Here, which also includes Apple, Samsung, Uber, Baidu, Alibaba, Tencent, and Alibaba, as well as a consortium of unnamed carmakers. However, a few things recommend Facebook as the most likely winner -- most notably, the fact that it already has a deal with Nokia to incorporate Here into its mobile Web platform, and appears to be using …

It may well have been the most boring boxing match in history, but the Mayweather vs. Pacquiao fight received a lot of attention on Twitter -- even if a lot of it was just people voicing regret that they had paid $100 to see the soporific showdown on pay-per-view courtesy of HBO and Showtime, or "pay per snooze" as some dubbed it. By comparison, the weekend's other big sporting event -- the Kentucky Derby -- was a pipsqueak on social media.

One of the best things about social media -- how easy it makes connecting with people -- is also one of the worst things, at least when it comes to the institution of marriage.
