When Secret first launched earlier this year, the only subscribers who could see your anonymous missives on the app were folks who were somehow connected to your phone's address book -- they were either your friends, friends of friends or friends of friends of friends (you get the idea). Now, however, Secret has loosened that restriction just a touch with the introduction of Facebook login support. Now if you sign up with Facebook on the app, you'll be able to spill your secrets to all your Facebook friends who are also on Secret. Of course, the company promises that no personal information is ever shared and you'll still be completely anonymous. On the one hand, this lets those of us who have more friends on Facebook than on our phone's address book see more Friend posts on Secret. On the other, it does give us a tiny bit of the creeps. Thankfully, the feature is completely optional, so you don't have to participate if you don't want to.Secret also announced another feature today called Collections, which are simply daily digests of posts from a certain category. You can go to Secret's brand-new web interface and subscribe to any of the available Collections -- current categories include Popular, Dating, Reflections, Funny, Work and Loss. If you do subscribe, you'll get secrets from that collection in your Explore stream. This definitely narrows the kinds of posts you see on Explore quite a bit, and it seems like it lets you home in more on what you prefer to see. According to the folks at Secret, they're still experimenting on how to give users more control over what they see on Explore, which can be a rather daunting task given the growing popularity of the network. If that sounds like something you'd be interested in, head on over to the source link to find out more. Don't worry, we won't tell anyone.
