So.. I'm a member on these 2 communities: inbound.org and growthhackers.com
One of the reason I'm reading a thread on those sites is because someone I recognize contributed to that particular thread.
(Not because of the author)
Let's say there's one member who always answers other people's questions. And his posts are usually so good so that every time he posted, I want to read it. The easiest way I can know whether he has contributed or not is by looking at his avatar, right?
That's why I think contributor's avatar is important in thread list. (at least more important than the OP's)
Well it doesn't have to show all contributors' avatars. Maybe about 3... and prioritize people we followed (if there will be a feature to follow people).
What do you guys think?
