Just how the heck do I track Pinterest? It's not easy, and it's that way on purpose. But Curalate is rigorously working to provide image-based brand analytics that are super-useful and insightful... even without the convenience of an API. Thank heavens for persistent entrepreneurs.

Facebook gunning to kill cookies. Tracking cookies, that is, and Google's the bull's eye. The übersocnet is developing something called "Optimized CPM" (optimized cost-per-thousand impressions), which will enable Facebook to track all users' Web activity while they're signed in to their Facebook accounts. They don't even need to have the site open: As long as they forget to log out, Facebook can gather valuable behavioral data that can be use for more effective on-site advertising. Our tendency to stay connected is probably way more reliable than an old-school tracking cookie, which is easily deleted every time you clear your cache. Freaky! But typically Facebook.

People are Tweeting about... JWT's launched a fun interactive site depicting the world's most-tweeted brands. Drill down by country or segment (tech, retail, travel, etc.), and have fun: Each color represents a brand, and you'll get handy stats as your cursor grazes over each. Great moment to ask yourself how much space you'll be taking up next year. Here are the top-tweeted brands for the United States (all segments):

Who does well on Facebook, anyhow? An apt question, given how often the algorithm changes (and not necessarily always in brands' favor). Readwrite.com's prepared a synopsis of five big tech companies that are killing it on Facebook, including observations on why each may be doing well. To wit: "To avoid spamming millions of people with irrelevant products, [Amazon] tends to choose general-interest items and use Facebook to publicize special sales. Amazon also asks a lot of questions, which is an effective—if patently obvious—way to drive up comments."

Analytics all the livelong day. Google and KISSmetrics are partnering to launch My Analytics, an app that lets you check (and share!) your Google Analytics metrics from your mobile devices. Now, number-crunching won't just be confined to your desk—and all the better, because how often have you wanted to prove a massive quantitative point in the middle of a meeting? (Also, it's better than sitting there sending text messages.)

Champions: made, not born. Social Business News has compiled the five essential qualities of a social business champion. Passion, innovativeness, and the ability to collaborate are the Top 3, but read the article for elaboration on each quality.

Watch your wallets, YouTubers! YouTube plans to launch paid subscriptions for channels in what AdAge is calling its "latest attempt to lure content producers, eyeballs, and advertiser dollars away from traditional TV, according to multiple people familiar with the plans." A small group of channel producers have been asked to submit applications to launch channels that users will be able to access only via paid subscription. These initial offerings will cost anywhere between $1 and $5 a month. Content libraries, self-help, financial advice, and pay-per-view-style live events may also add fees. We just hope the how-tos don't get paywalled because otherwise we'll never learn to cook another meal... or apply eyeshadow.
