As long as you follow the guidelines Jeff laid out on Attribution Required you should be able to display as much content as you want.
- Visually indicate that the content is from Stack Overflow, Meta Stack Overflow, Server Fault, or Super User in some way. It doesn’t have to be obnoxious; a discreet text blurb is fine. 2. Hyperlink directly to the original question on the source site (e.g., http://stackoverflow.com/questions/12345https://stackoverflow.com/questions/12345) 3. Show the author names for every question and answer 4. Hyperlink each author name directly back to their user profile page on the source site (e.g., http://stackoverflow.com/users/12345/usernamehttps://stackoverflow.com/users/12345/username)
One other detail from that post that's worth noting is that the links must not be nofollowed.
It should also be fine to display any meta-data about each post (views, votes, favorites, etc.), as it's the content that requires attribution.
