About the avatar position on topic list on mobile

2015 discussion about this so we don’t repeat ourselves

Information Overload - Some insight through qualitative interviews

I think it is unavoidable, unless we show both the avatar of the topic creator as well as the last poster – which would be very busy – we have to pick either Topic creator Last poster I think creator is more problematic because it will stay the same forever, even if there are hundreds of replies over a period of a week it would always be the same avatar displaying. So I agree with @sam on this one it has to be last poster. Last poster is more dynamic and more interesting over time.

Also in 2016

On the mobile theme, the list of posts show's the latest replying user's avatar, not the OP's avatar

This is by design, and has been discussed in other topics. When there is only room for one avatar in the topic list (as in mobile), the last person to talk in that topic is the correct avatar to show for the topic, otherwise a topic with 5000 replies would show the same avatar for months.
