Pivoting is a part of life for startups. But, generally speaking, most entrepreneurs aren’t going to go out of their way to pivot right when their business starts taking off

Desperate to increase video chat usage, Facebook is testing out a “Call” button  on top of people’s timeline profiles. I don’t think I’ve received a Facebook video chat since F acebook partnered with Skype to launch the feature a year ago, but now that might change. If a friend is online on the desktop version of Facebook, those in the test see a “Call” button next to that friends name on their profile , while previously a tiny videocamera icon in the text chat window was basically the only way to start a video chat.

Facebook is testing a subtle change to its search bar to now include the phrase “Search for people, places and things.” Previously, the bar only included the word “search.” As far as we can tell, there is no difference in how search results are now displayed, but the difference in wording could have an impact on how people use the feature.

Founder Eric Lagier is hoping to make his Internet time machine service Memolane more social today by allowing users to create shared “lanes” with their Facebook friends. The idea behind Memolane: People are usually sharing content on multiple sites, but it’s not always easy to browser olde content, or to look at content from multiple sites in one place. So for example, after I sign up and connected various social network accounts, I can browse and search a single timeline with photos from Facebook and Instagram, mixed in with my tweets and Foursquare check-ins

Every single Facebook user is or will soon be seeing a link at the top of their desktop news feed asking them to ”Stay in control of your account by following these simple security tips”. The link leads to the the Facebook Security page where users are taught how to spot a scam, pick a unique password, and most interestingly, confirm their mobile phone number for account recovery.
