The weekend read

Ready to hang up your skates this week? If this week has felt like you've been competing in the Olympics without a medal in sight, get on this podium called the weekend. I'll award you this list of carefully curated finds, reads and leads collected and shared on Twitter this week:

• Go for the gold: LinkedIn published a small business survey of ways that sector is using the site to drive growth.
• Live coverage: Here's a new Sony camera lens you can attach to your smartphone or tablet. Would you try this?
• Not tears of joy: An NBC reporter is accused of badgering U.S. Olympic skier Bode Miller about his dead brother until he cried on camera. Way to go.
• Instant replay: Lifehacker to the rescue, this time with how to take screenshots on almost any Kindle device.
• A perfect score: Ever wonder what's happening at Netflix when we all start binge-watching House of Cards? Wonder no more.
• Power through the skate: You can put call-to-action buttons to your Facebook Page posts with the same Power Editor that FB advertisers use. You're welcome.
• That thin ice you've heard about: I hate to break it to you, but just because someone shared your post doesn't mean they read it.
• The crowd goes wild: Elon Musk says that Tesla's brand wouldn't have bounced back after a series of car fires without social media.
• Long program: LinkedIn's now letting anyone--not just "influencers"--publish long posts.
• The ultimate test? A long look here at the popular Buzzfeed quizzes. Would you try this?
• The road to the Olympics: Here's a peek at a new open-source mapping tool in development, with an eye to using maps for storytelling.
• The roar of the crowd: More in new tools: Audio Memos app for recording and editing interviews.

Workshop reminder: Registration closes tonight at 12 midnight ET for the Washington, DC, workshop. Seats are still available! I'm offering a new workshop on women and public speaking. Be The Eloquent Woman will take place in Washington, DC, on Feb. 28, and in Oxford, UK, on April 2. The day-long workshop will help you build confidence and competence as a speaker, and help you subvert the expectations that many women face when they speak.
