On June 7th we'll be releasing two new views of content that will allow you to rapidly see what's new on the site as well as identify content that has gone unanswered. The next step for this (after this release) will be to add in personalization so that you can filter content based on your tag and member "following" preferences.
With this release we've done a few things with subscriptions
1. Exposed personalization settings so you can control how and when you receive the email subscription notifications. See the image below
2. The ability to selectively subscribe to email notification for content by Tag. At the top of the "Browse by Tag" page there is a new link to Subscribe with Email.
This is the first of several postings on the release coming March 15th
Questions vs. Articles
We now have the ability to distinguish, at posting time, between a "Question" and an "Article". These two types of postings will exhibit different behaviors that we think will optimize the experience of the user.
