Home(page) renovation. In an effort to encourage return visits from the 150 million Internet users who visit Twitter every month without signing in, the social media giant has revamped its home page. Now, instead of just “a background photo, a few lines of text, and a prompt to sign up or log in,” Twitter’s home page features boxes with the names of several of the platform’s most popular content topics, including “Actors & Actresses,” “Cute Animals” and “General News Sources.” A click on one of the boxes will take you to a timeline of tweets from some of the most popular commentators who tweet on that topic. Whether the new homepage will be enough to help Twitter expand its active-user base remains to be seen. LexBlog’s Kevin O’Keefe thinks that, to get more attorneys to join, the platform will need to go a few steps further by breaking down its content into niche areas of law.

Teen traffic. A new Pew Research study shows that Facebook is still the most popular social media platform among the members of an age group that many companies consider a crucial target market: 13- to 17-year-olds. Of the 1060 teens surveyed, 71% reported using Facebook. Snapchat, the vanishing messaging app that seems to be make news almost every day (for some reason or other) is up there (41%), too, right behind the photo sharing site Instagram (52%). Interestingly, teens from households with incomes greater than $75,000 are much more likely than teens whose families earn less than $30,000 to call Snapchat their top social media platform (14% compared to 7%). And teenage girls are more likely than teenage boys to use what Pew classified as “visually-oriented social media platforms”: Instagram (61% of girls vs. 44% of boys); Snapchat (51% of girls vs. 31% of boys); online pinboards like Pinterest (33% of girls vs. 11% of boys); and Tumblr (23% of girls vs. 5% of boys).

Rules for the nude and rude. Instagram has amended its Community Guidelines, which formerly simply asked users to be polite and respectful, to specify that the photo sharing platform will remove “content that contains credible threats or hate speech, content that targets private individuals to degrade or shame them, personal information meant to blackmail or harass someone, and repeated unwanted messages.” Instagram also amended its original guidelines to amplify its blanket prohibition on nudity. The new guidelines specify that Instagram will allow nudity in photos of paintings and sculptures, and “photos of post-mastectomy scarring and women actively breastfeeding,” but will not allow “close-ups of fully nude buttocks.” And, in the interest of discouraging users from posting images that they have “copied or collected from the Internet,” something the platform’s guidelines always proscribed, the new guidelines contain a link to a page that informs users about their intellectual property rights. But Techcrunch notes that because Instagram, unlike Youtube, still “doesn’t offer any copyright fingerprinting system to automatically remove infringing media,” there remains a gap between the photo sharing platform’s intellectual property policy and its enforcement.
