Icon size in feeds

Hi,

I am using the latest version of Social Media Feather (1.6)

I set my icons to be of size 24×24 as you can see here: http://www.tripletremelo.com/spacewalk-selfie-makes-waves-2/

But on my feed, the images used are 48×48 instead: http://www.tripletremelo.com/feed/

I think this is intended as discussed in http://wordpress.org/support/topic/responsive-icon-size?replies=8

But when using one of the RSS feed clients (e.g. Newsify on iPhone), the icons are really displayed with 48×48 (looks big). Is this intentional?

Thanks
